[alsa-devel] Zoom R16 (USB) again
by Jani Frilander 25 Oct '10

25 Oct '10

Hello all, I've been trying to make Zoom R16 multi track recorder / audio interface / control surface working with Linux without any success. I've tried this quirk, but it usually just hang the unit: { /* ZOOM R16 in USB 2.0 mode */ USB_DEVICE(0x1686, 0x00dd), .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { .ifnum = QUIRK_ANY_INTERFACE, .type = QUIRK_COMPOSITE, .data = (const struct snd_usb_audio_quirk[]) { { .ifnum = 0, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = 1, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = 2, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = 3, .type = QUIRK_MIDI_STANDARD_INTERFACE }, { .ifnum = -1 }, } } }, This one doesn't freeze it, but it neither works. No sound with playback. { /* ZOOM R16 in USB 2.0 mode */ USB_DEVICE(0x1686, 0x00dd), .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { .ifnum = QUIRK_ANY_INTERFACE, .type = QUIRK_COMPOSITE, .data = (const struct snd_usb_audio_quirk[]) { { .ifnum = 0, .type = QUIRK_AUDIO_STANDARD_INTERFACE, }, { .ifnum = 1, .type = QUIRK_AUDIO_FIXED_ENDPOINT, .data = &(const struct audioformat) { .formats = SNDRV_PCM_FMTBIT_S24_3LE, .channels = 2, .iface = 1, .altsetting = 1, .altset_idx = 1, .attributes = UAC_EP_CS_ATTR_SAMPLE_RATE, .endpoint = 0x03, .ep_attr = 0x01, .maxpacksize = 0x6c, .rates = SNDRV_PCM_RATE_44100 | SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_88200 | SNDRV_PCM_RATE_96000, .rate_min = 44100, .rate_max = 96000, .nr_rates = 4, .rate_table = (unsigned int[]) { 44100, 48000, 88200, 96000 } } }, { .ifnum = 2, .type = QUIRK_AUDIO_STANDARD_INTERFACE }, { .ifnum = 3, .type = QUIRK_MIDI_STANDARD_INTERFACE }, { .ifnum = -1 }, } } }, I attached the lsusb -v output.

[alsa-devel] MIDI support for hda-intel
by Nick Lloyd 25 Oct '10

25 Oct '10

Hi, quick question for the list. Has MIDI support been implemented for the hda-intel codec, specifically the sigmatel codec. I tried playing a MIDI file the other day, and could see the levels bouncing around, but no sound whatsoever. Basically, does the driver not support it, or am I doing something wrong? Thanks, Nick -- "Life is not measured by the number of breaths we take, but by the moments that take our breath away."

[alsa-devel] SoC Atmel SSC stereo problem
by Patrick Ziegler 25 Oct '10

25 Oct '10

Hi, I have some trouble with stereo audio through the atmal ssc interface based on at91-ssc.c. Unfortunately left and right channels were swapped periodically. In my environment the codec supplies the BLCK and LRC clocks and the SSC is configured to transmit one sample on both edges of the LRC clock. But I guess the audio frames will always start with a frame of the left channel while the LRC clock is in an undefined state. How does normally the audio driver detect when a left and when a right channel frame should be send and with which it should start ? Thanks in advance for your help. Regards, Patrick -- Dipl.-Inf.

[alsa-devel] snd-hda-intel + ad198x is broken with 2.6.36
by Vasily Khoruzhick 25 Oct '10

25 Oct '10

Hi, it seems something in 2.6.36 broke sound for snd-hda-intel with ad198x codecs (reproducible with Lenovo 3000 N100 laptop, AD1986A codec and with HP Compaq 6910p, AD1981 codec). I have no problems with 2.6.35 kernel. Sound works right after power on, but after reboot or even driver reload it does not work until power cycle, of course controls are unmuted. Under "does not work" I mean that aplay plays nothing, but gives no errors. What info would be usefull to debug this issue? Regards Vasily

[alsa-devel] Constraining the number of frames per period
by Adam Rosenberg 25 Oct '10

25 Oct '10

I would like to make sure that all programs that use the sound driver I wrote are required to use 512 frames per period. Is there a snd_pcm_hw_constraint function that will allow me to do this? If not, is this possible another way? Thanks, Adam Adam Rosenberg Software Engineer Alcorn McBride Inc. 3300 South Hiawassee Building 105 Orlando, FL 32835 (407) 296 - 5800 ext. 5490

[alsa-devel] [PATCHv2] ASoC: Overhaul Samsung drivers
by Jassi Brar 25 Oct '10

25 Oct '10

From: Jassi Brar <jassi.brar(a)samsung.com> Hi, Submitting revised patch series. Patches 11 through 16 apply to Kgene's tree, rest apply to Mark Brown's. Since v1: a) Use case 16 in set_bfs and default for error b) Better code comments. c) Use switch case in i2sv2_i2s_set_clkdiv d) Use SNDRV_PCM_RATE_8000_96000 e) MAX_I2S -> SAMSUNG_I2S_SECOFF f) Local namespace cleanup with i2s driver. ------------ Here come patches overhauling the Samsung ASoC support. The AC97, PCM, SPDIF and ASoC-DMA related code has merely undergone cosmetic changes - symbol, device & driver renaming and file moving. A new I2S controller driver has been added to manage Samsung SoCs since S3C64XX. Older driver has been changed only as is necessary. Regarding I2S, I have left the s3c24xx series untouched because the controllers are too different to run by a common driver. S3C2412's I2S does have some similarities, but not important enough to warrant impact on new driver design. The new I2S driver has been designed around the notion of features/quirks. The newer SoCs have revised version of I2S_0(usually) than previous ones. So, I2S block is 'specified' in the platform code and the driver works on that configuration. For now, Secondary I2S DAI works only with System-DMAC. I2S-Internal DMA and SRAM will be enabled later. Testing:- Simple testing of 5.1 channel and hardware mixing seems to work (though there seems to be some issue with symmetric_rates in soc-core.c which would be tried to fix later as saperate issue). I would appreciate any test-results for GONI and SMARTQ. I suggest the patches 13,14,16 & 17 go via Kgene's Tree, and the rest via ASoC tree due to tight dependencies. 1). ASoC: Samsung: Remove redundant AQUILA driver 2). ASoC: Samsung: Rename DMA device 3). ARM: Samsung: Define common audio-dma device 4). ASoC: Samsung: Rename ASoC DMA driver 5). ASoC: Samsung: Rename AC97 platform device 6). ASoC: Samsung: Rename AC97 driver 7). ASoC: Samsung: Rename PCM driver 8). ASoC: Samsung: Generalize DMA driver namespace 9). ASoC: Samsung: Rename s3c64xx I2S device 10). ASoC: Samsung: Add common I2S driver 11). ARM: S3C64XX: I2S: Upgrade platform device 12). ARM: S5P6440: I2S: Upgrade platform device 13). ARM: S5P6442: I2S: Upgrade platform device 14). ARM: S5PC100: I2S: Upgrade platform device 15). ARM: S5PV210: I2S: Upgrade platform device 16). ARM: S5PV310: Add audio platform devices 17). ASoC: SMARTQ: Move to use new I2S driver 18). ASoC: GONI: Move to use new I2S driver 19). ASoC: SMDK64XX: Move to use new I2S driver 20). ASoC: S3C64XX: Remove obsoleted I2S drivers 21). ASoC: SMDK64XX: Rename for other platforms 22). ASoC: SMDK_WM8580: Enable for SMDKC100 23). ASoC: Samsung: Generalize Kconfig symbols 24). ASoC: Samsung: Rename from s3c24xx to samsung Thanks, Jassi

[alsa-devel] Weird sound issue on 2.6.36
by Felipe Contreras 25 Oct '10

25 Oct '10

Hi, I suddenly noticed that sound is not working on 2.6.36; there's no error, or warning, everything seems to be working, but there's no sound coming out. I tried the rc's and AFAICR it was working fine, maybe I changed the config, but everything seems to be ok. I went back to the rc's and still couldn't get them to work. 2.6.35.7 works though. I'm attaching the config. -- Felipe Contreras

[alsa-devel] alsactl adds volume controls?
by David Henningsson 24 Oct '10

24 Oct '10

So I've discovered that my sound card has a "PCM Playback Volume" control, but changing that control does not alter the volume. This is not only confusing but also a problem for PulseAudio. (PA merges this control into it's overall volume, and so when the user moves PA's volume control, in some ranges nothing happens.) Interestingly enough, this control does not come from the HDA parser, it is added by alsactl at boot time...! (Through alsa-lib's snd_ctl_elem_add_integer, which does an snd_ctl_ioctl.) So the question is, why is alsactl creating volume controls, and why is userspace allowed to add controls in the first place, if the kernel can't use them for anything anyway? That doesn't make sense to me. This a generic problem, but sound card info, if that matters, is available here: https://launchpad.net/bugs/625149 Codec: http://launchpadlibrarian.net/54478760/Card0.Codecs.codec.0.txt -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic

[alsa-devel] S51 usb support
by Mandar Joshi 23 Oct '10

23 Oct '10

> Hmm, there is no feature unit in this dump, so the volume is most > probably set with an vendor-specific USB request. Unless the Windows > driver does something similar than PulseAudio and handles the volume > level control in software (iow, modify each sample before sending it to > the hardware) rather than setting any actual hardware volume level. Daniel, you are right, Its the driver thing. Feb 2009, I was dealing this the same issue and James Courtier-Dutton from this list pointed out that the device has no hardware based mixer controls which is why alsamixer does not find anything. He suggested using SoftVol. I've been using dmix and Softvol for volume control whenever I need it. This is the ~/.asoundrc I use http://mndar.phpnet.us/usbxfi/files/asoundrc.log The device has a volume knob. I had left the issue of the volume knob alone until a few days back.. I was about the post this when I came across the query from Matti Picus. This is how it works. The volume knob sends an interrupt via endpoint 0x83 containing 0xC0 0x00 whenever it is rotated clockwise,anti-clockwise or pressed. After this a control message is sent to the device to retrieve which of the 3 actions it was. The control packet sent is 0xa1 0x85 0x00 0x00 0x00 0x00 0x04 0x00 We get a 1 byte response. 0x0F for anti-clockwise rotation. 0x0D for press and 0x10 for clockwise rotation. I've tested this using a simple kernel module to handle just the volume knob and it works fine. The quick little code I've written does the above, then sets a sysfs attribute and sends a kobject_uevent. Udev rules execute a command depending on the value of this sysfs attribute. (Having some issues here but anyway...) Since the volume is entirely a software thing, I figure this might be a good way of letting userspace know about the volume knob. Using softvol we can have a Master volume control and then we can use a command like amixer in udev rules to change the volume. Or since events are passed to HAL, something could be done there. I do not know much about the usbaudio driver but does this seem like something that can be done from within the usbaudio driver ? -Mandar Joshi

[alsa-devel] RME MADIface 192 kHz problem

Hi all, I have a problem running the RME MADIface card at 192 kHz. At that speed the number of channels for the card is reduced to 16. I can set the sampling rate to 192 kHz using: # amixer -c 1 cset numid=2 9 numid=2,iface=MIXER,name='Sample Clock Source' ; type=ENUMERATED,access=rw------,values=1,items=10 ; Item #0 'AutoSync' ; Item #1 'Internal 32.0 kHz' ; Item #2 'Internal 44.1 kHz' ; Item #3 'Internal 48.0 kHz' ; Item #4 'Internal 64.0 kHz' ; Item #5 'Internal 88.2 kHz' ; Item #6 'Internal 96.0 kHz' ; Item #7 'Internal 128.0 kHz' ; Item #8 'Internal 176.4 kHz' ; Item #9 'Internal 192.0 kHz' : values=9 but when I try to read data at 192 kHz I always get a : Invalid argument from the snd_pcm_hw_params_set_channels(...) and snd_pcm_hw_params(...) functions when I try to set the number of channels. The snd_pcm_hw_params_get_channels_max(...) snd_pcm_hw_params_get_channels_min(...) functions also seems to return the wrong number of max and min number of channels. And, jackd will not start using 192 kHz. See the thread here: http://www.rme-audio.de/forum/viewtopic.php?id=9169 What is needed to get this card running at 192 kHz?

Hello, I have a sound problem with an HP DV8 (HP Pavilion DV8-1290-ez). I have two sound cards 01:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1) and 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05) the sound works properly with the internal speakers of the laptop, but nothing comes from external speakers. Here are the dtails of my laptop config : http://www.alsa-project.org/db/?f=de70b54ecd18f28494b08e05d865779b9776686b I think i have no sound with mic in amsn or skype. Waiting for your response. With my best regards.

[alsa-devel] [PATCH 11/25] ASoC: Samsung: Add common I2S driver
by Jassi Brar 22 Oct '10

22 Oct '10

From: Jassi Brar <jassi.brar(a)samsung.com> The I2S controllers since S3C64XX are incremental revisions, with a new feature added to the last one. The programming i/f doesn't conflict between these revisions, so it is possible to have one common driver that could manage various versions of I2S (v3, 4 & 5) Signed-off-by: Jassi Brar <jassi.brar(a)samsung.com> --- arch/arm/plat-samsung/include/plat/audio.h | 24 + sound/soc/s3c24xx/Kconfig | 3 + sound/soc/s3c24xx/Makefile | 2 + sound/soc/s3c24xx/i2s.c | 1251 ++++++++++++++++++++++++++++ sound/soc/s3c24xx/i2s.h | 29 + 5 files changed, 1309 insertions(+), 0 deletions(-) create mode 100644 sound/soc/s3c24xx/i2s.c create mode 100644 sound/soc/s3c24xx/i2s.h diff --git a/arch/arm/plat-samsung/include/plat/audio.h b/arch/arm/plat-samsung/include/plat/audio.h index e32f9ed..b72ad03 100644 --- a/arch/arm/plat-samsung/include/plat/audio.h +++ b/arch/arm/plat-samsung/include/plat/audio.h @@ -16,10 +16,34 @@ #define S3C64XX_AC97_GPE 1 extern void s3c64xx_ac97_setup_gpio(int); +struct samsung_i2s { +/* If the Primary DAI has 5.1 Channels */ +#define QUIRK_PRI_6CHAN (1 << 0) +/* If the I2S block has a Stereo Overlay Channel */ +#define QUIRK_SEC_DAI (1 << 1) +/* + * If the I2S block has no internal prescalar or MUX (I2SMOD[10] bit) + * The Machine driver must provide suitably set clock to the I2S block. + */ +#define QUIRK_NO_MUXPSR (1 << 2) +#define QUIRK_NEED_RSTCLR (1 << 3) + /* Quirks of the I2S controller */ + u32 quirks; + + /* + * Array of clock names that can be used to generate I2S signals. + * Also corresponds to clocks of I2SMOD[10] + */ + const char **src_clk; +}; + /** * struct s3c_audio_pdata - common platform data for audio device drivers * @cfg_gpio: Callback function to setup mux'ed pins in I2S/PCM/AC97 mode */ struct s3c_audio_pdata { int (*cfg_gpio)(struct platform_device *); + union { + struct samsung_i2s i2s; + } type; }; diff --git a/sound/soc/s3c24xx/Kconfig b/sound/soc/s3c24xx/Kconfig index 6efdf65..20fe288 100644 --- a/sound/soc/s3c24xx/Kconfig +++ b/sound/soc/s3c24xx/Kconfig @@ -40,6 +40,9 @@ config SND_S5P_SOC_SPDIF tristate select SND_SOC_SPDIF +config SND_SAMSUNG_I2S + tristate + config SND_S3C24XX_SOC_NEO1973_WM8753 tristate "SoC I2S Audio support for NEO1973 - WM8753" depends on SND_S3C24XX_SOC && MACH_NEO1973_GTA01 diff --git a/sound/soc/s3c24xx/Makefile b/sound/soc/s3c24xx/Makefile index 93de2a0..1d6fc07 100644 --- a/sound/soc/s3c24xx/Makefile +++ b/sound/soc/s3c24xx/Makefile @@ -8,6 +8,7 @@ snd-soc-s3c64xx-i2s-v4-objs := s3c64xx-i2s-v4.o snd-soc-s3c-i2s-v2-objs := s3c-i2s-v2.o snd-soc-samsung-spdif-objs := spdif.o snd-soc-pcm-objs := pcm.o +snd-soc-i2s-objs := i2s.o obj-$(CONFIG_SND_S3C24XX_SOC) += snd-soc-s3c24xx.o obj-$(CONFIG_SND_S3C24XX_SOC_I2S) += snd-soc-s3c24xx-i2s.o @@ -18,6 +19,7 @@ obj-$(CONFIG_SND_S3C64XX_SOC_I2S_V4) += snd-soc-s3c64xx-i2s-v4.o obj-$(CONFIG_SND_S3C_I2SV2_SOC) += snd-soc-s3c-i2s-v2.o obj-$(CONFIG_SND_S5P_SOC_SPDIF) += snd-soc-samsung-spdif.o obj-$(CONFIG_SND_S3C_SOC_PCM) += snd-soc-pcm.o +obj-$(CONFIG_SND_SAMSUNG_I2S) += snd-soc-i2s.o # S3C24XX Machine Support snd-soc-jive-wm8750-objs := jive_wm8750.o diff --git a/sound/soc/s3c24xx/i2s.c b/sound/soc/s3c24xx/i2s.c new file mode 100644 index 0000000..6869f51 --- /dev/null +++ b/sound/soc/s3c24xx/i2s.c @@ -0,0 +1,1251 @@ +/* sound/soc/s3c24xx/i2s.c + * + * ALSA SoC Audio Layer - Samsung I2S Controller driver + * + * Copyright (c) 2010 Samsung Electronics Co.

[alsa-devel] hda-intel (ALC889) - sound loops/repeats continuously, and general brokenness
by Juliano F. Ravasi 22 Oct '10

22 Oct '10

Hello ALSA devs, (Cc'ing alsa-devel since looks like it can be a driver problem/bug, but still unsure. Need some expert advice.) I'm experiencing a lot of problems reproducing audio with an HD Audio "card" integrated on an Intel DX58SO mainboard. It happens only on this card, everything is Ok with another (USB) card. The most visible problem is that `aplay` plays only a small fragment of audio (less than one second), then hangs and the card keeps reproducing that fragment continuously in a loop, until killed with Ctrl-C. `aplay -N` progresses, but each fragment repeats 3 times. Doing an strace on `aplay`, it hangs here while repeating the audio fragment: ... semop(294912, {{0, 0, 0}, {0, 1, SEM_UNDO}}, 2) = 0 semop(294912, {{0, -1, SEM_UNDO|IPC_NOWAIT}}, 1) = 0 ioctl(4, 0x4122, 0x3) = 0 ioctl(4, 0x4122, 0) = 0 ioctl(4, 0x4122, 0xe4) = 0 poll([{fd=3, events=POLLIN|POLLERR|POLLNVAL}], 1, -1) = 1 ([{fd=3, revents=POLLIN}]) ioctl(4, 0x4122, 0x3) = 0 ioctl(4, 0x4122, 0xe4) = 0 ioctl(4, 0x4122, 0x1) = 0 read(3, "\6\0\0\0\1\210\377\377\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\1\210\377\377"..., 128) = 64 read(3, 0x7fff890f6810, 128) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=3, events=POLLIN|POLLERR|POLLNVAL}], 1, -1^C <unfinished ...> Descriptor 3 is /dev/snd/timer ... Perhaps time stops progressing for the driver? `aplay -N` continues a little here because this poll() call timeouts after 1000ms, but this still repeats each fragment 3 times. Other audio software (mplayer, amarok) can play audio almost normally, except when you pause. When paused, the same behavior happens: the last fragment of sound before pausing keeps repeating continuously until unpaused. When the song finishes, the application (tested with mplayer) also hangs, the last fragment keeps repeating while the process is blocked here: ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig -icanon -echo ...}) = 0 ioctl(0, SNDCTL_TMR_START or TCSETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(6, 0x4144^C <unfinished ...> Descriptor 6 is /dev/snd/pcmC0D0p , and 0x4144 is SNDRV_PCM_IOCTL_DRAIN ioctl in sound/asound.h. Sometimes mplayer timeouts and reports: [AO_ALSA] alsa-lib: pcm_hw.c:616:(snd_pcm_hw_drain) SNDRV_PCM_IOCTL_DRAIN failed (-5): Input/output error I'm at a loss here. I have already read the sound/alsa/HD-Audio.txt and tried many of the tweaks described there, but with no luck. Any help is greatly appreciated.

[alsa-devel] Question regarding snd_pcm_control_ioctl
by Bensaid, Selma 22 Oct '10

22 Oct '10

Hi, I have question concerning ALSA Core snd_pcm_control_ioctl function. I have noticed that the IOCTL fails if it's called for a device with substream_count = 0, since I'm implementing a PCM device that supports Record and does not support Playback, the IOCTL fails when called for the Playback stream. I would propose, in such case, to return that the stream has 0 playback substreams instead of failing. Thanks in advance for your help, Regards, Selma. --------------------------------------------------------------------- Intel Corporation SAS (French simplified joint stock company) Registered headquarters: "Les Montalets"- 2, rue de Paris, 92196 Meudon Cedex, France Registration Number: 302 456 199 R.C.S.

[alsa-devel] [PATCH 00/25] ASoC: Overhaul Samsung drivers
by Jassi Brar 22 Oct '10

22 Oct '10

From: Jassi Brar <jassi.brar(a)samsung.com> Hi, Here come patches overhauling the Samsung ASoC support. The AC97, PCM, SPDIF and ASoC-DMA related code has merely undergone cosmetic changes - symbol, device & driver renaming and file moving. A new I2S controller driver has been added to manage Samsung SoCs since S3C64XX. Older driver has been changed only as is necessary. Regarding I2S, I have left the s3c24xx series untouched because the controllers are too different to run by a common driver. S3C2412's I2S does have some similarities, but not important enough to warrant impact on new driver design. The new I2S driver has been designed around the notion of features/quirks. The newer SoCs have revised version of I2S_0(usually) than previous ones. So, I2S block is 'specified' in the platform code and the driver works on that configuration. For now, Secondary I2S DAI works only with System-DMAC. I2S-Internal DMA and SRAM will be enabled later. Testing:- Simple testing of 5.1 channel and hardware mixing seems to work (though there seems to be some issue with symmetric_rates in soc-core.c which would be tried to fix later as saperate issue). I would appreciate any test-results for GONI and SMARTQ. I suggest the patches 13,14,16 & 17 go via Kgene's Tree, and the rest via ASoC tree due to tight dependencies. 1). ASoC: WM8580: Remove useless assignment 2). ASoC: Samsung: Remove redundant AQUILA driver 3). ASoC: Samsung: Rename DMA device 4). ARM: Samsung: Define common audio-dma device 5). ASoC: Samsung: Rename ASoC DMA driver 6). ASoC: Samsung: Rename AC97 platform device 7). ASoC: Samsung: Rename AC97 driver 8). ASoC: Samsung: Rename PCM driver 9). ASoC: Samsung: Generalize DMA driver namespace 10). ASoC: Samsung: Rename s3c64xx I2S device 11). ASoC: Samsung: Add common I2S driver 12). ARM: S3C64XX: I2S: Upgrade platform device 13). ARM: S5P6440: I2S: Upgrade platform device 14). ARM: S5P6442: I2S: Upgrade platform device 15). ARM: S5PC100: I2S: Upgrade platform device 16). ARM: S5PV210: I2S: Upgrade platform device 17). ARM: S5PV310: Add audio platform devices 18). ASoC: SMARTQ: Move to use new I2S driver 19). ASoC: GONI: Move to use new I2S driver 20). ASoC: SMDK64XX: Move to use new I2S driver 21). ASoC: S3C64XX: Remove obsoleted I2S drivers 22). ASoC: SMDK64XX: Rename for other platforms 23). ASoC: SMDK_WM8580: Enable for SMDKC100 24). ASoC: Samsung: Generalize Kconfig symbols 25). ASoC: Samsung: Rename from s3c24xx to samsung Thanks, Jassi

[alsa-devel] how to mandate the use of PCM plugin?
by Stas Sergeev 22 Oct '10

22 Oct '10

Hi guys. Is it possible to somehow mandate the use of a PCM plugin? For example, the PC-Speaker.conf defines the use of softvol plugin for "default" and "front" devices. It is still possible for the software to bypass it by the use of "hw", and some software does exactly that. Is it possible to somehow make some plugin a mandatory?

[alsa-devel] Status of UCM
by Tobin Davis 22 Oct '10

22 Oct '10

I have been looking into UCM lately and have been tasked with looking into possible inclusion in Ubuntu Natty 11.04 timeframe, for arm mainly, but more systems may be possible depending on the scope of the project. Unfortunately there isn't much info online other than a few brief blurbs. Reading the patch logs gives me a little more insight, but a timeline would really be nice. -- Tobin Davis Perhaps the biggest disappointments were the ones you expected anyway.

[alsa-devel] [PATCH 07/22] pcmcia: move config_{base, index, regs} to struct pcmcia_device
by Dominik Brodowski 21 Oct '10

21 Oct '10

Several drivers prefer to explicitly set config_{base,index,regs}, formerly known as ConfigBase, ConfigIndex and Present. Instead of passing these values inside config_req_t, store it in struct pcmcia_device.

[alsa-devel] [PATCH 06/22] pcmcia: simplify IntType
by Dominik Brodowski 21 Oct '10

21 Oct '10

IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO (all other drivers). As this flags seems to relate to ioport access, make it conditional to the driver having requested IO port access. There are two drivers which do not request IO ports, but did set INT_MEMORY_AND_IO: ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

[alsa-devel] [patch 3/3] Staging: sst: fixups in SNDRV_SST_STREAM_DECODE
by Dan Carpenter 21 Oct '10

21 Oct '10

This is another patch about copying data to the kernel before using it. SNDRV_SST_STREAM_DECODE is sort of tricky because we need to do a copy_from_user() that gives us another two pointers and we have copy those.

[alsa-devel] snd-usb-audio for Radikal Technologies SAC-2K
by Raphaël Doursenaud 20 Oct '10

20 Oct '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm working on getting the usb part of this very nice control surface to work with alsa. I sniffed the usb traffic of the windows driver then browsed the snd-usb-audio source code for clues. I managed to get it partially working using a modified QUIRK_MIDI_EMAGIC since the protocols are fairly similar (at least the 0xF5 port switching part). Please find attached the patch I came up to. I have a few problems and dark areas I hope you'll be able to light up a little : First, I more or less get the picture of what the code is doing but there's one part I fiddled with that I don't understand fully. What are the .out_cables and .in_cables bitmasks doing besides defining the number of ports ? Next, the input part seem to work flawlessly on all ports, but I have what seems to be a buffer overflow on the device when outputting midi data. Comparing the windows and linux usb traffic, something obvious shows up : the windows driver seem to be waiting for the device's acknowledgment after each sent byte before sending the next one while the snd-usb-audio module sends a bunch of bytes at once that ends up confusing the device _and_ module. How can I make it behave like the windows driver ? I have traffic and error logs available if needed. Thanks. - -- Raphaël Doursenaud http://raphael.doursenaud.fr -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAky+oqQACgkQaZKmNAdXaVUopgCgifnK+eSsCNpR5rx21iUqmXBQ wJIAoJlt4h7Tp8tYYSbg9ZfLekE1QQfL =d7vi -----END PGP SIGNATURE-----

[alsa-devel] PATCH[1/1] Add I2S common driver for Intel MID platform
by Le Gall, Louis 20 Oct '10

20 Oct '10

Hi, This patch set is for new I2S SSP common driver that supports I2S audio on Intel MID platforms. It is used for sending/receving I2S audio samples on Intel MID platform. This interface is mostly used on Intel MID platforms and provide the low level interface for some upper layer drivers such as Alsa sound card driver for Bluetooth/FM peripherals, char device interfaces for modem (cmt_speech),... As this is used to transfer speech frames from/to cellular modem that have specific timing constraints (and modem also uses the I2S path to send some side-info), the Alsa SoC interface cannot be used. It is based on low level part of cmt_speech driver that can be found in N900 (see http://lists.meego.com/pipermail/meego-kernel/2010-September/000078.html ). The intel_mid_i2s have been separated from cmt_speech in order to be more generic and to be used on other ports (for instance, to provide Alsa sound card driver for Bluetooth and FM). Upper level drivers cmt_speech and Alsa sound card driver that uses intel_mid_i2s will be up-streamed in coming days and is planned to use the same folder path (sound/pci/intel_mid_i2s/). So once these files will be upstream, this will provides Alsa sound driver interface for Bluetooth and FM for Intel Mid platform, and specific speech audio interface (char device) that is used by lib cmt speech data. I will provide soon some draft version of example driver that uses intel_mid_i2s so reviewers can have better understanding of how it is used and how it fits together. Best Regards, Louis Le Gall Here is a simple diagram that explain where is the intel_mid_i2s in software architecture. +-----------+ | | |Pulse Audio| | | | | +-----------+ | | +------------+------------+ | | | | | | +-----------+ +-----------+ | | |Lib cmt | |Alsa Lib |------+ |speech |------+ | | | |data | | | | | | | | +-----------+ | +-----------+ | | | | | | | User ......|............|.........................|................................. | | | Kernel | | | | | | | | | | | | | | | | | | \|/ \|/ \|/ V V V +---------+ ++---------++ ++---------++ | | ||Alsa snd || ||cmt || |Intel SST| ||driver || ||speech || | "MAD" | ||SSP || ||driver || | | ||BT/FM || || || +---------+ ++---------++ ++---------++ | | | | | | | | | | | | \|/ | \|/ V | V +-----------+ | ++---------++ | | | \ ||intel mid|| |LPE | +------------------>||i2s || | | / ||unified || | | ||driver || +-----------+ ++---------++ | | | | Kernel ......|......................................|................................. | | Hardware \|/ \|/ V V +-- --+ +-- --+ | | | | |MISC | |SSP in I2S | | | |config | | | | | +-- --+ +-- --+

I will take us little time for that :-) Meanwhile IMO it would be great to have this driver in staging or in sound whichever you guys agree to ~Vinod

[alsa-devel] Newbie needs help to understand SNDRV_PCM_TRIGGER_START?
by Radivoje Jovanovic 19 Oct '10

19 Oct '10

I am writing my first ALSA driver. We have hardware where the amp is controlled with another CPU (non Linux) so I have to forward the buffers from ALSA to it. We do not have working solution on another CPU so I cannot test sound playback yet. ALSA hits trigger method in my driver and soon after it leaves my trigger method throws an null pointer exception (probably since I did not do anything in my trigger method). I am wondering if the ALSA will call SNDRV_PCM_TRIGGER_START every single time new buffer is available. Do I need to manage circular queue of buffers or ALSA is doing this for me already? Thanx

[alsa-devel] [PATCH 04/25] ARM: Samsung: Define common audio-dma device
by Jassi Brar 19 Oct '10

[alsa-devel] [PATCH 03/25] ASoC: Samsung: Rename DMA device
by Jassi Brar 19 Oct '10

19 Oct '10

From: Jassi Brar <jassi.brar(a)samsung.com> Some Samsung SoCs have a PCM(DSP) controller. So the name s3c24xx-pcm-audio for DMA driver is not very appropraite.

[alsa-devel] [PATCH 02/25] ASoC: Samsung: Remove redundant AQUILA driver
by Jassi Brar 19 Oct '10

19 Oct '10

From: Jassi Brar <jassi.brar(a)samsung.com> AQUILA and GONI are essentially the same h/w w.r.t ASoC. They only differ by the fact that GONI has stereo speaker-out whereas AQUILA has mono. The difference can easily be handled in the same MACHINE driver by making machine-specific runtime changes.

IIRC at least one version had a split where the ALSA integration stuff was separated out from the underlying DSP interface code - that was pretty helpful since it helps focus on the ALSA specifics. > I did think about it, but what history we have is fairly basic because > it was basically written then fired in my direction to help sort out Yeah, I wasn't thinking about history so much as about helping break down the areas covered for comprehensibility. > > To be honest all this stuff looks sufficiently generic that it might > > be worth considering factoring out an abstraction which can be used by > > other offload engines - having a standard kernel API for them would > > be a real win.

We ought to be able to come up with something for the core streaming stuff, though. Like I say, it's just a nice to have though. > So are you happy for it to go into staging.

Probably best to look for feedback from at least Takashi and/or Jaroslav as well, but obviously we can update the TODO later. I do have some nervousness about the concept of staging for embedded stuff since I worry that inclusion in staging can send the wrong message to vendors but that's a completely separate issue to this driver.

[alsa-devel] [PATCH] Per Application Volume Control plugin for ALSA
by James Huk 19 Oct '10

19 Oct '10

Hello everybody. This is my first "post" here, so please be "gentle". I have created PAVC plugin for ALSA, it is based on COPY plugin, and use SOFTVOL plugin for sound output. As far as I can tell from current tests - It works perfectly, and it doesn't break compatibility with any apps I use (and PulseAudio does). So I was wondering - is there any chance this plugin would be added to the next official ALSA release? Here is the patch that enables it on current alsa-lib-1.0.23 (hopefully this mailing list is a good place to "post" this): --- a/configure.in 2010-09-23 17:03:00.000000000 +0200 +++ b/configure.in 2010-09-23 17:09:11.029900400 +0200 @@ -445,7 +445,7 @@ pcm_plugins="" fi -PCM_PLUGIN_LIST="copy linear route mulaw alaw adpcm rate plug multi shm file null empty share meter hooks lfloat ladspa dmix dshare dsnoop asym iec958 softvol extplug ioplug mmap_emul" +PCM_PLUGIN_LIST="copy linear route mulaw alaw adpcm rate plug multi shm file null empty share meter hooks lfloat ladspa dmix dshare dsnoop asym iec958 softvol extplug ioplug mmap_emul pavc" build_pcm_plugin="no" for t in $PCM_PLUGIN_LIST; do @@ -516,6 +516,7 @@ AM_CONDITIONAL(BUILD_PCM_PLUGIN_EXTPLUG, test x$build_pcm_extplug = xyes) AM_CONDITIONAL(BUILD_PCM_PLUGIN_IOPLUG, test x$build_pcm_ioplug = xyes) AM_CONDITIONAL(BUILD_PCM_PLUGIN_MMAP_EMUL, test x$build_pcm_mmap_emul = xyes) +AM_CONDITIONAL(BUILD_PCM_PLUGIN_PAVC, test x$build_pcm_pavc = xyes) dnl Defines for plug plugin if test "$build_pcm_rate" = "yes"; then --- a/src/pcm/Makefile.am 2010-04-16 13:11:05.000000000 +0200 +++ b/src/pcm/Makefile.am 2010-09-23 17:20:10.601899695 +0200 @@ -102,6 +102,9 @@ if BUILD_PCM_PLUGIN_MMAP_EMUL libpcm_la_SOURCES += pcm_mmap_emul.c endif +if BUILD_PCM_PLUGIN_PAVC +libpcm_la_SOURCES += pcm_pavc.c +endif EXTRA_DIST = pcm_dmix_i386.c pcm_dmix_x86_64.c pcm_dmix_generic.c --- a/src/pcm/pcm.c 2010-04-16 13:11:05.000000000 +0200 +++ b/src/pcm/pcm.c 2010-09-23 17:10:43.813900406 +0200 @@ -2047,7 +2047,7 @@ static const char *const build_in_pcms[] = { "adpcm", "alaw", "copy", "dmix", "file", "hooks", "hw", "ladspa", "lfloat", "linear", "meter", "mulaw", "multi", "null", "empty", "plug", "rate", "route", "share", - "shm", "dsnoop", "dshare", "asym", "iec958", "softvol", "mmap_emul", + "shm", "dsnoop", "dshare", "asym", "iec958", "softvol", "mmap_emul","pavc", NULL }; --- a/include/pcm.h 2010-04-16 13:11:05.000000000 +0200 +++ b/include/pcm.h 2010-09-23 17:11:58.389899158 +0200 @@ -376,7 +376,9 @@ SND_PCM_TYPE_EXTPLUG, /** Mmap-emulation plugin */ SND_PCM_TYPE_MMAP_EMUL, - SND_PCM_TYPE_LAST = SND_PCM_TYPE_MMAP_EMUL + /** PAVC plugin */ + SND_PCM_TYPE_PAVC, + SND_PCM_TYPE_LAST = SND_PCM_TYPE_PAVC }; /** PCM type */ --- a/src/pcm/pcm_pavc.c +++ b/src/pcm/pcm_pavc.c @@ -0,0 +1,846 @@ +/* + * PCM - PAVC plugin + * Based on PCM - Copy conversion plugin by Abramo Bagnara <abramo(a)alsa-project.org> + * + * Copyright (c) 2010 by Adrian Kobyliński <huk256(a)gmail.com> + * + * This library is free software; you can redistribute it and/or modify + * it under the terms of the GNU Lesser General Public License as + * published by the Free Software Foundation; either version 2.1 of + * the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

PIDs of apps that currently use softvol channels are saved to ~/.softvol/SOFTVOLXX.pid, so this can be checked at any time. If some application will try to restart only its sound subsystem, PAVC plugin will check those files to determine if it should be connected to the new softvol channel, or the one it currently uses. I tried to mimic the way this works with OSS4. Current limitations: -Since there is no "mute and slider at the same time" support in SOFTVOL plugin - there is no mute switch for software channels (or maybe there is a way I don't know about?) -Software channels must be named SOFTVOL00,01,02 and so on -SOFTVOL channels have both PLAYBACK and CAPTURE capabilities by default - this makes some mixers go haywire, and display double sliders - maybe there is a way around this I don't know about (like setting PLAYBACK only capability)? -Code of PAVC, could probably look nicer Hopefully someone will take a look at this, of course I am open to suggestions and critics. Best regards. P.S Sorry for my English ;]

Hi Julian, You might like to refer to this thread: http://www.avrfreaks.net/index.php?name=PNphpBB2&file=printview&t=88432&sta… As I have found out, it is not necessary to have the same EP number for IN and OUT for rate feedback to work with a Linux or OSX host. This may be a requirement for Vista/Win7 hosts though. We are still doing testing. Alex

[alsa-devel] report bug in kernel sound driver
by Zhang, Wenjie 18 Oct '10

18 Oct '10

Dear all i want report a bug in davinci sound device driver (sound/soc/davinci-pcm.c) This bug cause by DMA copy Overflow. It will cause kernel oops with a lot of unusual info. And this problem seem still in latest stable kernel (version 2.6.35.7) Bug Symptom at the end of mail Here is my analyse of this bug: Device will call function : davinci_pcm_new This function will malloc a lagre Continuous Pages buffer (Typicly:128K) both Playback and Capture. Those two buffer will use as DMA copy ! When someone recoder sound date ! This driver will use DMA.Copy register date to Capture buffer that malloc at function davinci_pcm_new ! every DMA copy finish.callback function davinci_pcm_dma_irq will run. function davinci_pcm_enqueue_dma will work.This function will set DMA copy params again. And problem is in here ! It set DMA params : src = sound recoder 32-bit reg address dst = prtd->period * period_size src_bidx = 0 //(Every dma copy finish the src will not change) dst_bidx = data_type; //date_type = 2, because only high 16-bit is the sound date. acnt = 4 bcnt = 2048 cnt = 1 Use this param.DMA Internal work like: for(c=0;c<cnt;c++) { for(b=0;b<bcnt;b++) { memcopy(&dst,&src,4) src += src_bidx; //src_bidx = 0; dst += dst_bidx //dst_bidx = data_type =2 16bit sound date } } This copy will make all dst buffer has source high 16 bit date. but will cause 2 byptes Overflow every time the dma copy finish. it will change 4K bytes + 2 bytes. The 2 bytes is DMA copy Overflow. it will not error until you copy to the last period! because. your date total copy 128K +2bytes . and we only malloc 128K bytes other 2 bytes is kernel space memory. this two bytes will be use random by kernel. And those 2 bytes copy by dma. kernel don't know anything about this segment default.

Why do you distinguish that way? Is your device initialised in High Speed mode whenever it's connected to a Linux host? Regards, Julian

That would be wonderful :) Greg was kind enough to stage it in his staging and there is some activity going on there as well. If you feel this is good enough to go ahead to sound tree, please merge.

[alsa-devel] [PATCH 1/2] Version-check libtool correctly when doing an out-of-tree build
by Simon McVittie 17 Oct '10

17 Oct '10

libtool is only created at the end of ./configure, so it doesn't make sense to grep it in ./configure (the check would always fail the first time). However, ltmain.sh is copied into the ${srcdir} by libtoolize and should be safe to check at any time that configure can be run.

[alsa-devel] [PATCH] alsa-utils: speaker-test: fix infinite loop
by David Henningsson 17 Oct '10

17 Oct '10

I'm using speaker-test in an Ubuntu-specific bug triaging script/application ("ubuntu-bug audio"), and without showing the terminal that speaker-test outputs. So when the stream cannot be opened for one reason or another, my application hangs indefinitely and the user cannot report the bug. Looking at the code, seems like Takashi removed all error loops except this one four years ago, so there shouldn't be any controversy in removing this one as well. -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic

This patch series is tested on OMAP3 & 4 and yet to be tested on OMAP2. There are few clarifications required so that the next patch series can be implemented after aligning. 1. Audio layer is making use of mcbsp and it's dma base addresses and is closely coupled with omap-mcbsp. This can be handled either by a. providing an API with which Audio layer can get these addresses. (or) b. move the plat-omap/mcbsp.c and mach-omap2/mcbsp.c to sound/soc/omap/ [1] Option (a) would only be a workaround to handle the situation. As audio is the only user for mcbsp, option (b) is better. If option(b) is agreed upon, the same can be addressed on top of the mcbsp hwmod series. 2. Sidetone feature is available only in OMAP3 (McBSP2&3) which has different base address and sys configs compared to it's mcbsp port. Hence the mcbsp is considered as a single device with two hwmods for McBSP2&3 devices in OMAP3. 3. Autoidle needs to be disabled for sidetone before enabling the sidetone feature. There was a design proposed by Kishon [2] to add an API in hwmod to modify the autoidle bit but was not agreed upon. How do we handle this situation where the device has to disable or enable the autoidle bit at runtime? [1] https://patchwork.kernel.org/patch/225582/ [2] https://patchwork.kernel.org/patch/134371/ We would resend the same patch series by including alsa mailing list (alsa-devel(a)alsa-project.org) <<snip>>

[alsa-devel] Need expert's advice - Fast Track Ultra (8R) dropping samples
by Felix Homann 15 Oct '10

15 Oct '10

Hi, in that past months I've been trying get the Fast Track Ultra devices working properly in Alsa. We've had lots of progress, most of the code has moved to Alsa git and today I've even posted a patch for getting mixer support for these devices. Now, I need to get some expert's advice: The devices seem to drop samples or frames. Here's a report I've got today on the M-Audio forum: "I've got a subtle problem to report: I think audio playback is dropping sample frames. To hear the problem, open Audacity at 48 kHz and play a 10-kHz. sine wave. When I do that I hear a regular clicking sound, about four clicks a second. I've tried recording the output and if I'm seeing correctly, exactly one sample frame in every 13312 (13x1024) is being dropped on output. I don't see anything similar on input. When either jack or Pd has both the input and the output open, the delay from input to output gradually decreases until it forces occasional sync errors. (I haven't tried this with audacity though.)" (see http://forums.m-audio.com/showthread.php?714-Not-a-problem.-FastTrack-on-li…) I could reproduce it on my machines, even at 44.1 kHz. The clicking sound is very subtle, it goes unnoticed when not listening to pure sines without attention to clicks. How can this be sorted out. Any ideas? Kind regards, Felix

[alsa-devel] snd_mixer_load error with composite USB device
by Alex 15 Oct '10

15 Oct '10

Hi Daniel and Clemens, I have been testing the sdr-widget and when alsamixer is run, there is a snd_mixer_load error - Invalid Argument. The sdr-widget firmware with UAC1 descriptors works under Windows for audio control (muting and volume). The UAC2 firmware works under Linux and OSX for audio control as well. However, firmware with UAC1 does not work under Linux for audio control. I traced the error to the fact that the sdr-widget enumerates as a composite USB device and the audio control interface is not interface #0. The current Linux driver for UAC1 appears to assume that the audio control interface is #0. It should not make that assumption. Alex

[alsa-devel] [PATCH v3 0/3] ASoC AC97 audio support for ep93xx
by Mika Westerberg 15 Oct '10

15 Oct '10

Hi, This series adds AC97 audio support for Cirrus Logic EP93xx family SoCs. Example machine driver is for Simplemachines Sim.One (which is the only hardware that I have which has AC97 codec). Changes the previous version: - rebased against latest ASoC tree (added support for multicomponent ASoC) - fixed according comments by Mark Brown - patch 1/4 (DMA fix) is now in ARM tree so dropped from this series. Thanks, MW Mika Westerberg (3): ASoC: add ep93xx AC97 audio driver ARM: ep93xx: add AC97 platform support ASoC: ep93xx: add Simplemachines Sim.One AC97 audio support arch/arm/mach-ep93xx/core.c | 34 ++ arch/arm/mach-ep93xx/include/mach/ep93xx-regs.h | 1 + arch/arm/mach-ep93xx/include/mach/platform.h | 1 + arch/arm/mach-ep93xx/simone.c | 1 + sound/soc/ep93xx/Kconfig | 16 +- sound/soc/ep93xx/Makefile | 4 + sound/soc/ep93xx/ep93xx-ac97.c | 468 +++++++++++++++++++++++ sound/soc/ep93xx/simone.c | 89 +++++ 8 files changed, 613 insertions(+), 1 deletions(-) create mode 100644 sound/soc/ep93xx/ep93xx-ac97.c create mode 100644 sound/soc/ep93xx/simone.c

Mark, can you pick up this patch for us? Because it depends on "powerpc: rename immap_86xx.h to fsl_guts.h, and add 85xx support", it will break the build if we apply to powerpc-next.

Hello, i've a problem about to install 32 soundcards on my linux server (centos 5.3) i tried all ways but i fail all times to run 32 soundcards at the same time. after that i googled on the internet then find the text about that. is it possible to run 32 soundcards same time on my server? if yes how could i do that thank you for your helps... - ALSA: Fix limit of 8 PCM devices in SNDRV_CTL_IOCTL_PCM_NEXT_DEVICE When compiled with CONFIG_SND_DYNAMIC_MINORS the ALSA core is fineto have more than 8 PCM devices per card, except one place - theSNDRV_CTL_IOCTL_PCM_NEXT_DEVICE ioctl, which will not enumeratedevices > 7. This patch fixes the issue, changing the devices list organisation.

So far I only support one fixed sample rate (48 kHz) in the device. Regarding the sync I am wondering how to determine the alignment of the data coming from USB. Is there some way to be sure that the data frames do start with the left channel when reading them from USB? The output to the I2S is done in bigger chunks through the DMA engine of the AT91SAM7 - it might be possible that I loose one packet in some case at this place... This would actually cause a inversion on the channels... > As for i2s for the DAC etc, u need to have the right timing for the various > clocks.

Covers even more than I want to do. My goal is only to have a 192kHz/24bit USB->I2S brige which can be used for high quality audio designs. If I would have seen your project before I might not even have started working on this. Well, now it's topic of my bachelor thesis, so I really should get this done (c: Regards, Julian

[alsa-devel] USB asynchronous mode feedback format
by Julian Scheel 14 Oct '10

14 Oct '10

Hi, I am currently working on an USB-Audio device based on a AT91SAM7 processor. Actually I am currently trying to get the asynchronous mode working, to be able to use the AT91SAM7 as I2S transmitter in slave mode, utilizing and external clock. So I added the endpoint descriptors for the Feedback pipe. I attached the lsusb output. Alsa detects the card properly and reports it to be async in the /proc/asound interface. Now for a first tested I am trying to report back a constant rate through the feedback pipe. The stream is 48kHz with 16Bit. Reading the USB Audio 1.0 spec I assume in theory for a 48kHz stream I would report a rate of 48 samples per frame to the host, compensated by the measured drift. As the data should be 10.14 encoded I currently send { 0x0c, 0x00, 0x00 } on the feedback pipe whenever it is queried, which happens whenever I try to play some stream on this device. But unfortunately the host won't send any data to the device. I am wondering what might be wrong and where to check that alsa received the feedback data properly? I would be really thankful for any help! Regards, Julian

[alsa-devel] [PATCH v3 1/6] ARM: S5P: Reduce duplicated EPLL control codes
by Seungwhan Youn 14 Oct '10

14 Oct '10

S5P Samsung SoCs has a EPLL to support various PLL clock sources for other H/W blocks. Until now, to control EPLL, each of SoCs make their own functions in 'mach-s5pxxx/clock.c'. But some of functions, 'xxx_epll_get_rate()' and 'xxx_epll_enable()', are exactly same in all S5P SoCs, so this patch move these duplicated codes to common EPLL functions that use platform wide. Signed-off-by: Seungwhan Youn <sw.youn(a)samsung.com> --- This patch is re-worked followings, requested by Kukjin Kim, from v2 :- o Set re-define S5P_EPLL_CON with specific EPLL definations on S5P platform. o and, keep original EPLL definations.

[alsa-devel] [PATCH v5] ASoC/2.6.37: fix au1x platform
by Manuel Lauss 13 Oct '10

13 Oct '10

This patch fixes up the au1x audio platform after the multi-component merge: - compile fixes and updates to get DB1200 platform audio working again, - removal of global variables in AC97/I2S/DMA(PCM) modules. The AC97 part is limited to one instance only for now due to issues with getting at driver data in the soc_ac97_ops. Signed-off-by: Manuel Lauss <manuel.lauss(a)googlemail.com> --- v5: smaller patch v4: fixed a bug in the previous bugfix, and added DAI drvdata accessors. v3: fixed a bug which caused cat /proc/iomem to loop endlessly. v2: prepare PCM,I2S for multiple card operation, use dev_name() for DAI name. Against Liam's asoc/for-2.6.37 branch. Tested on DB1200 and DB1300 (here both I2S and AC97 operate as independent cards), please fold this into the other Au1x multi-component patches. Issues I observed with AC97: * AC97 is limited to a single instance since I cannot get at the driver data in the AC97 callbacks at all time (or did I miss anything?): when the AC97 codec calls snd_ac97_mixer(), it calls into the soc_ac97_ops callbacks; however ac97->bus->card->private_data (suggested by Mark) is _always_ NULL, so no way to get at the dai and ultimately driver data. * generic AC97 codec use spits out this kobject warning, which is caused by the "device_register()" in soc-core.c::soc_ac97_dev_register(): asoc: ac97-hifi <-> au1xpsc-ac97.1 mapping ok kobject (8fdc59b0): tried to init an initialized object, something is seriously wrong.

[alsa-devel] [PATCH 1/2] ASoC: Pay attention to driver supplied DAI IDs
by Mark Brown 13 Oct '10

[alsa-devel] [PATCH] ASoC: Add WM8962 microphone bias control
by Mark Brown 13 Oct '10

We unconditionally require SYSCLK since while only microphone detection specifically requires SYSCLK any actual use case would enable it via some other means but microphone detection may have nothing active other than the bias itself.

If the sound card does not support multi-streaming , the mic is one of the choice in the "Capture Source" controls If your application can find "Input Source" in your sound card , this mean that your sound card support multi-streaming capture i.e. there will be more than one "Input Source" controls

We know that the only possible error that is currently returned is -EINTR though, so we could do a similar trick and define another #define __cond_mutex(x, c) ((!c) ?

I've given it a try, wrapping the trylock/interruptible/killable variants into macros and the number of additional warnings was much less than I had feared.

However, the card appears to have a dedicated a analogue gain stage just for the headphones. It's not a full PGA, but can be set to 0db, -6db, -12dB and mute - under windows.

I've not contributed to a project like this before... The obvious ones to me are of course the driver itself, and adding a new radio button to hdspconf. Is there anything else? Thanks a lot, Matt

[alsa-devel] Alsamixer-Qt4 0.5.0 released
by Sebastian H. 11 Oct '10

11 Oct '10

Hello again After an almost complete rewrite to support separate channels views in the main sliders and switches areas, Alsamixer-Qt4 0.5.0 is now available. http://xwmw.org/alsamixer-qt4/ http://sourceforge.net/projects/alsamixer-qt4/files/ This is a snapshot from the CHANGELOG file. * The channels mixer dialog is gone * Mixer elements can be toggled between joined and channels view * Automated switch from joined to channels view if channels values differ for a certain time * New context menus for mixer elements * New dynamic support for the Alsa is_active element flag * New command line arguments similar to the console alsamixer ones * The card selection widget got basic support for Alsa plugins * GUI cleanups and slight style changes * Reduced CPU usage by showing QSpinBox widgets only on demand (mouse over) * Fixed a forgotten debug timer that was always running in 0.4.1 (constant 1% CPU usage) I ran several tests but since a lot of code has been rewritten there still may be regressions or even new bugs. There're also some implemented features I couldn't test at all because my rather basic hardware doesn't support it. - Mixer elements with more than two channels. If the sliders arrangement or some graphics for your card with 32 channels per element look weird, please drop me a note and/or a screenshot. - Is-active flag In theory the mixer should support dynamic hiding and revealing of elements whose is-active flag changes. If it doesn't or even crashes, please tell. Any comments are welcome. Best, Sebastian H.

The method you're using to generate the patches is pretty much orthogonal to anything else, except of course in the case where you're also submitting the automation for checking (which is useful where possible).

[alsa-devel] RME HDSP9632, mute headphones
by Matthew Robbetts 11 Oct '10

11 Oct '10

Hi all, I've just acquired myself a HDSP9632 and noticed what I think is a missing feature from the drivers (compared to Windows, at least): the ability to set the headphones to "mute", in addition to -6dB and -12dB of gain. I would find this feature useful. Is there a reason it is missing or has it just been overlooked? Or, alternatively, am I doing something stupid? I'm using the alsa that comes with kernel 2.6.36-rc5 (I think it is 1.0.21?). Thanks a lot, Matt

Hi, I wanted to set my input sources and control volume through the mixer api from a 'C' code. I am required to do this without using alsa utils. Please guide me as to how I can set my input source to say 'Mic' and also adjust say Front Right channel volume. It would also be nice if there was a mini tutorial on the alsa page which explains how to do this basic stuff. Thanks and Regards, Chandrashekhar

[alsa-devel] [PATCH] ASoC: Use delayed work for debounce of GPIO based jacks
by Mark Brown 10 Oct '10

10 Oct '10

Rather than block the workqueue by sleeping to do the debounce use delayed work to implement the debounce time. This should also mean that we extend the debounce time on each new bounce, potentially allowing shorter debounce times for clean insertions.

[alsa-devel] [PATCH] ASoC: omap: Remove needless prints from machine drivers
by Jarkko Nikula 10 Oct '10

10 Oct '10

It is currently completely normal to execute these machine drivers code on different boards if the kernel includes support for multiple boards so no error message should be printed if the machine_is_xxx does not match with the machine driver. Therefore remove these pr_err and pr_debug prints in those cases.

[alsa-devel] proposed change to amidi: allow data from stdin
by Al Steffens 10 Oct '10

10 Oct '10

ALSA Developers, Proposed change to amidi: allow data from stdin. A simple addition to amidi to allow midi commands from standard input would facilitate a MIDI-over-IP setup in which amidi and netcat together could send/receive raw MIDI over a network, or the internet. I'm thinking of something as simple as nc host port | amidi -p hw:1,0 to receive raw midi from someone on the internet and pipe the midi commands to one of my tone generators. This would further the effort to realize the "online jamming" idea with MIDI. Currently, amidi will read raw MIDI commands from a file using the "-s" flag. I have tried this with a named pipe, but amidi tries to get the file size causing an error. Perhaps fixing this would be one solution. Al Steffens apsteffe(a)netwood.net

[alsa-devel] Headphone jack and auto-mute of speak output
by Davyd McColl 09 Oct '10

09 Oct '10

Good day I'm new to this list (though I've done some searching, I'm sure I could have missed something), so please bear with me. I filed a bug report recently against Ubuntu with respect to the problem I'm experiencing (as per the subject: jacking in my headphones doesn't mute the speaker output) and was informed that the decision had been made upstream as a design intention. I was linked off to: http://mailman.alsa-project.org/pipermail/alsa-devel/2010-August/030071.html with respect to the thread on this topic. I'd like to raise it again though, perhaps as a configurable feature, for the following reasons: 1) headphones muting the speakers used to work some time ago (before Ubuntu 9.04, iirc), so we have an established user expectation even under Linux distros. 2) headphones mute the built-in speakers of my laptop (windows and ubuntu) -- why the inconsistent behaviour for a desktop? Just because the speakers in the laptop are bolted into the frame of the machine? 3) Windows "gets it right": plugging in headphones mutes external speakers -- it's convenient (Though I think you can disable that feature if you want). I'm told by a person at work that his Mac does the same. Again, the user expectation is unmet under a newish Linux distro. 4) The user expectation theory is held up by the number of bug reports against this design choice on Ubuntu Launchpad alone (I haven't looked at other bug lists). The average user is not expecting the current behaviour, obviously 5) For people without hardware volume controls on their speakers, the problem is exacerbated: instead of being able to plug in headphones to disturb others around them less (ie: contain their music/noises), they have to unplug their speakers too -- which may not be trivial since speakers are normally plugged in at the back of the machine, not at the front where the headphone jack would be found. On a machine in an enclosure, this is especially troublesome. So I'd really like to know if it would be possible to allow the behaviour most users are expecting. Sometimes it's useful to be able to output to both speakers and headphones, but I would say that the average user doesn't want both at the same time. -d -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- The competent programmer is fully aware of the limited size of his own skull.

[alsa-devel] [PATCH 1/2] mfd: Factor out WM831x I2C I/O from the core driver
by Mark Brown 08 Oct '10

08 Oct '10

In preparation for the addition of SPI support for the WM831x move the I2C specific code into a separate file with a separate Kconfig option so the I2C support can be excluded from the build. Also update the 1133-EV1 PMIC module support for SMDK6410 to use the new symbol.

[alsa-devel] Problem configuring alsa-lib for cross-compilation
by Simon Brenner 08 Oct '10

08 Oct '10

Hi, I'm building and installing the alsa libs for an embedded system. My current process runs as follows: 1) the alsa-lib package is crosscompiled on my PC host system (x86); 2) the alsa-lib package is installed on a special prefix (say '/tmp/dest') on the host system; 3) some installed files are copied from the dir. '/tmp/dest' to the final target root filesystem tree (say '/tmp/emb_root'); Now there are a couple of details that do not work with this process: in point 1) I configure the alsa-lib package with the option --prefix=/tmp/dest because I want to install the package there and use it later to compile other packages against it (alsa-utils for example); at the same time I want also to use the alsa libs in my target system but it is not possible because, at runtime, the init functions in the libasound.so looks for its configuration file under '/tmp/dest/share/alsa/alsa.conf'! The same problem happens with the plugins dir. I tracked back this problems to the fact that, in the configure.in, the variable ALSA_CONFIG_DIR is used both to be substituted in the Makefile.am's (AC_SUBST(ALSA_CONFIG_DIR)) and to define the preprocessor constant in the 'include/config.h' (C_DEFINE_UNQUOTED(ALSA_CONFIG_DIR,...)). There is currently no way to have two independent values for the two cases. My current 'best' solution is to patch the header 'include/config.h' after running the configure script. Is there any standard solution to this without patching the configure results ? Regards, -Simon.

[alsa-devel] asihpi: Control naming
by Eliot Blennerhassett 07 Oct '10

07 Oct '10

Hi all, I'm struggling with getting the correct names for controls, so that they show up correctly in the Playback or Capture modes of alsamixer E.g. "PCM 3 Capture Meter" appears in the playback controls? How is capture vs playback display determined? or to put it another way: What are the rules for creating control names. Here is a reduced schematic of one of our cards (in reality more channels e.g. 4 physical stereo ins and outs, 12 players, 8 recorders) All players and inputs are mixed to outputs. All inputs and players multiplexed to each capture. How should all these controls be named?

[alsa-devel] X-Fi Xtreme Audio PCIe

Hello Alsa developers: We have 500 linux servers with X-Fi Xtreme Audio PCIe. The audio card is properly detected by kernel. The card is unmuted, the sound applications works fine. But the card doesn't sound. Googling I discover the same case on several forums, no solution. First Question: The driver is finished? Is it on development? Is it abandoned? Second Question: Can I join to driver development. I need to make work this soundcard. ---------------------------------------------------------------------------------- Distribution: Fedora 13 kernel 2.6.34.7-56.fc13.i686.PAE alsa version: alsa-lib-1.0.23 01:00.0 PCI bridge: Creative Labs [SB X-Fi Xtreme Audio] CA0110-IBG PCI to PCIe Bridge [root@localhost ~]# lsmod Module Size Used by snd_ctxfi 69769 0 fuse 47907 2 sunrpc 163601 1 ip6t_REJECT 3310 2 nf_conntrack_ipv6 14223 2 ip6table_filter 1199 1 ip6_tables 9774 1 ip6table_filter ipv6 221726 88 ip6t_REJECT,nf_conntrack_ipv6 uinput 5287 0 snd_hda_codec_ca0110 4769 1 snd_hda_intel 19995 0 iTCO_wdt 8940 0 iTCO_vendor_support 2027 1 iTCO_wdt snd_hda_codec 70968 2 snd_hda_codec_ca0110,snd_hda_intel snd_hwdep 4860 1 snd_hda_codec snd_seq 42775 0 snd_seq_device 5035 1 snd_seq dcdbas 6552 0 snd_pcm 62185 3 snd_ctxfi,snd_hda_intel,snd_hda_codec bnx2 57069 0 snd_timer 15391 2 snd_seq,snd_pcm power_meter 7602 0 snd 46591 9 snd_ctxfi,snd_hda_codec_ca0110,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_seq,snd_seq_device,snd_pcm,snd_timer soundcore 4934 1 snd snd_page_alloc 6097 3 snd_ctxfi,snd_hda_intel,snd_pcm microcode 10249 0

[alsa-devel] ### Question on HW Pointer
by Steve Spano 06 Oct '10

06 Oct '10

Hello Folks, I am wondering if someone can help clarify how the hw pointer is used by the ALSA layer. I have a 24 channel soundcard that we have developed, using a Xilinx fpga. The system is working, in that I can receive inbound samples on all 24 inputs and transmit samples on all 24 outputs. But something isn't completely right. We can xrun's and reports of very high cpu utilization.even though I know we are in and out of our interrupts within 100uS for a 2.7mS interrupt period. Interesting that our xruns cite a "0mS delay" or sometimes a 4mS delay (1.5 periods?) I think the issue has to do with how we are presenting the response to the hw-pointer request OR how/when we are calling the pcm_snd_elapsed. I think the flow should be as follows (lets consider the dac part) Step #1 ) interrupt occurs Step #2) dma/transfer begins as kicked off in interrupt routine Step #3) we advance the buffer pointer for the alsa buffer Step #4) we exit the interrupt . then the hardware should start advancing its pointer as it is reading the new samples .. then sometime later, the alsa layer calls the "hw_pointer" function And then we return the current value of the hardware pointer from the board? So alsa knows how many samples the board has processed from the interrupt? We should be pretty close, because it is working for the most part..but I think this pointer is not right. Can someone explain how this pointer/etc is supposed to flow and what alsa may be using it for? Maybe some latency calculation in a an upper layer? Thanks again Steve Spano

My X-FI Surround USB card is barely usable. pulseaudio will let me control the volume levels, alsa support cannot view any volume controls. How can I contribute to better support for this card under alsa? I would like to get to the point where amixer can control the analog input/output volume levels. I am a capable programmer, but know very little about alsa, where should I start? Matti

[alsa-devel] [PATCH] sst: Intel SST audio driver
by Alan Cox 05 Oct '10

05 Oct '10

From: Vinod Koul <vinod.koul(a)intel.com> This is the Intel SST audio driver. As compared to the previous versions it has all the printks and other stuff noted cleaned up and more hardware support. The Aava support is disabled in this patch (is_aava resolves to 0) because the Aava board detection logic is not yet upstream. The driver itself is a combination of a traditional ALSA driver and a hardware assisted offload driver which can play audio while the processor is asleep but which can't do all the more interactive stuff. In the general case most software would use the ALSA interface, but the other interface is needed for certain classes of use such as music playback on highly power consumption sensitive devices. This is going to staging primarily because it depends upon the staging memrar driver.
