[alsa-devel] [PATCH] [RFC] ASoC: OMAP: fix OMAP1510 broken PCM pointer callback
by Janusz Krzysztofik 30 Jun '09

30 Jun '09

This patch tries to work around the problem of broken OMAP1510 PCM playback pointer calculation by replacing DMA function call that incorrectly tries to read the value form DMA hardware with a value computed locally from an already maintained variable omap_runtime_data.period_index. Tested on OMAP5910 based Amstrad Delta (E3) using work in progress ASoC driver. Based on linux-2.6-asoc.git v2.6.31-rc1. Signed-off-by: Janusz Krzysztofik <jkrzyszt(a)tis.icnet.pl> --- It seems that on OMAP1510, DMA Channel Progress Counter registers (DMA_CPC_CH[0-8]) always contain values derived from DMA channels destination port address, even if constant, and there are no DMA registers available that would follow DMA channels source port address. Because of this limitation, current implementation of omap_get_dma_src_pos() for OMAP1510 is broken and doesn't seem to be easy correctable. --- linux-2.6.31-rc1/sound/soc/omap/omap-pcm.c.orig 2009-06-27 20:20:16.000000000 +0200 +++ linux-2.6.31-rc1/sound/soc/omap/omap-pcm.c 2009-06-27 23:21:42.000000000 +0200 @@ -216,12 +216,15 @@ static snd_pcm_uframes_t omap_pcm_pointe dma_addr_t ptr; snd_pcm_uframes_t offset; - if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK) - ptr = omap_get_dma_src_pos(prtd->dma_ch); - else + if (substream->stream == SNDRV_PCM_STREAM_CAPTURE) { ptr = omap_get_dma_dst_pos(prtd->dma_ch); + offset = bytes_to_frames(runtime, ptr - runtime->dma_addr); + } else if (!(cpu_is_omap1510())) { + ptr = omap_get_dma_src_pos(prtd->dma_ch); + offset = bytes_to_frames(runtime, ptr - runtime->dma_addr); + } else + offset = prtd->period_index * runtime->period_size; - offset = bytes_to_frames(runtime, ptr - runtime->dma_addr); if (offset >= runtime->buffer_size) offset = 0;

[alsa-devel] Can a phone hook switch follow alsa jack model?
by Janusz Krzysztofik 29 Jun '09

29 Jun '09

Hi, I am wondering if it is a good idea to create support for a phone hook switch, or a handset pick up switch, like that found on Amstrad E3 (Delta) videophone, using alsa jack framework. After my initial attempt to add support for the switch using gpio-keys driver, I am no longer sure if it is a good idea to follow the keyboard model, that the driver has been designed after, for driving a switch that has nothing to do with keyboards and may required a different approach. OTOH, the switch is closely related to a handset, and handsets can be seen as sound devices, can't they? So maybe alsa jack would fit better than keyboard? However, I am not sure if the switch in question matches the alsa jack model closely enough. I see the switch usage not as simple as turning handset microphone/speaker on or off. It can be used for other purposes as well, like accepting a phone call or actually dialing a number that has been just typed in. Furthermore, it can be used to turn off a speakerphone function, while, in turn, the related handset microphone/speaker pair can be turned off not only with this switch, but with a handsfree button as well, for example. All that extra functionality looks like belonging to userspace rather then kernel, not like other alsa jack implementations that seem to do all the job of switching media paths inside the kernel. That is why I am not sure if the jack model is suitable for the purpose.

[alsa-devel] IMX31 Audio Driver issue
by Harish Kumar 29 Jun '09

29 Jun '09

Hi, I am using a imx31 based board from Garz & fricke. I need to configure the audio driver from the linux 2.6.23 BSP available. I configured the audio driver by selecting the SSI, ALSA & PMIC Audio options in the kernel configuration. The PMIC Audio card is listing /proc/asound/cards and all the necessary devices are created using the udev available on the rootfs. I used the check_audio.out application available from IMX PDk BSP test programs. We are getting the following error. I am using the /unit_tests/check_audio.out 0 /unit_tests/audio8k16S.wav Hi... playing on /dev/sound/adsp (SSI1) Configuration : 16 8000 2 audio driver write error: Input/output error audio driver write error: Input/output error a The program is not exiting. also tried with SSI2 as below /unit_tests/check_audio.out 1 /unit_tests/audio8k16S.wav Hi... playing on /dev/sound/dsp (SSI2) Configuration : 16 8000 2 audio driver write error: Input/output error audio driver write error: Input/output error But the same hardware is working with WINCE without any issue. I feel there might be issues with drivers that i am using or may some configuration mismatch. Request your help in resolving the same. Request you to provide the troubleshooting steps so that issue can be resolved. The applications used and the capture of the command execution is as attached. Thanks & Regards Harish Kumar.B

[alsa-devel] warning "hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj."
by Simos Xenitellis 29 Jun '09

Hi All, I am getting the above warning when trying to play audio files. Contrary to other similar cases with this warning, in my case the playback of the media files fails. For every single media file, the playback fails after a random amount of time (a few seconds to a few minutes). I am running Ubuntu 9.04 (kernel 2.6.28-13-generic, x86_64, upgraded to Alsa 1.0.20 using AlsaUpgrade, http://ubuntuforums.org/showthread.php?p=6589810). I increased bdl_pos_adj to 32 and there is no effect (I added "options snd-hda-intel bdl_pos_adj=32" to /etc/modprobe.d/alsa-base.conf, then "/sbin/alsa force-reload"). lspci -vvv says: 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) Subsystem: Dell Device 02bb Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 2293 Region 0: Memory at f6500000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0+,D1-,D2-,D3hot+,D3cold+) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Capabilities: [60] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable+ Address: 00000000fee0300c Data: 41d1 Capabilities: [70] Express (v1) Root Complex Integrated Endpoint, MSI 00 DevCap: MaxPayload 128 bytes, PhantFunc 0, Latency L0s <64ns, L1 <1us ExtTag- RBE- FLReset+ DevCtl: Report errors: Correctable- Non-Fatal- Fatal- Unsupported- RlxdOrd- ExtTag- PhantFunc- AuxPwr- NoSnoop+ MaxPayload 128 bytes, MaxReadReq 128 bytes DevSta: CorrErr- UncorrErr- FatalErr- UnsuppReq- AuxPwr+ TransPend- LnkCap: Port #0, Speed unknown, Width x0, ASPM unknown, Latency L0 <64ns, L1 <1us ClockPM- Suprise- LLActRep- BwNot- LnkCtl: ASPM Disabled; Disabled- Retrain- CommClk- ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt- LnkSta: Speed unknown, Width x0, TrErr- Train- SlotClk- DLActive- BWMgmt- ABWMgmt- Capabilities: [100] Virtual Channel <?> Capabilities: [130] Root Complex Link <?> Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel lshw says: *-multimedia description: Audio device product: 82801I (ICH9 Family) HD Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 03 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=HDA Intel latency=0 module=snd_hda_intel Simos

Hi. Some time ago, I submitted a bug about the integrated micro of the USB webcam Philips SPC 530NC: record: pcm_read:1617: read error: Input/output error This is bug #4560: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4560 I would really appreciate if someone familiar with the USB audio system could give it some attention. It is probably very similar to bug #3927. Raymond seems to have been able to help somewhat, but the command that is said to work for the reporter does not work for me. Regards, -- Nicolas George

[alsa-devel] [PATCH 1/2] alsa/soc: Fix typo in MPC5200 PSC AC97 driver Kconfig
by Grant Likely 29 Jun '09

29 Jun '09

From: Grant Likely <grant.likely(a)secretlab.ca> ALSA SoC drivers should be specify SND_SOC_AC97_BUS instead, not AC97_BUS. Without SND_SOC_AC97_BUS defined, an AC97 device will not get correctly registered on the AC97 bus, which prevents thinks like the WM9712 touchscreen driver from getting probed.

I just got a macbookpro (mid2009 version) with a new nvidia chipset. there is no sound at all. neither via the built-in speakers nor via out-jack. i tried aplay -D myfile.wav with everything from aplay -L as well. i also tried a recent snapshot (alsa-driver-20090626.tar.bz2) as well as gentoo ebuilds alsa-headers-9999 and alsa-driver-9999 (which uses git to pull recent versions). so here's a little information i can gather: $ lspci -s 00:08.0 -v 00:08.0 Audio device: nVidia Corporation MCP79 High Definition Audio (rev b1) Subsystem: nVidia Corporation Device cb79 Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 23 Memory at d3480000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: HDA Intel Kernel modules: snd-hda-intel alsa-info: http://www.alsa-project.org/db/?f=80e89b82fec184b68a88b9ed4128544a276775fc modinfo snd-hda-intel: http://www.nopaste.com/p/a3B7miINP i also found a thread about that problem (w/o solution obviously): http://www.uluga.ubuntuforums.org/showthread.php?t=1188849&page=2 hope that's all information necessary. if i can i'd love to help in some way. thanks

[alsa-devel] Laptop speakers nonfunctional, jacks functional

---------- Forwarded message ---------- From: Ludwig Maes <ludwig.maes(a)gmail.com> Date: 2009/6/26 Subject: Laptop speakers nonfunctional, jacks functional To: alsa-user(a)lists.sourceforge.net Realtek ALC888S (according to preinstalled Realtek HD audio manager on windows) visible jacks working, builtin laptop speakers and subwoofer silent. Running Ubuntu 9.04 compiled and installed alsa 1.0.20. http://www.alsa-project.org/db/?f=fb64ba9a8ab28d8c16532ece21e3adba7219e4b9 Notice it thinks it is ALC1200. I searched this and found it in patch_realtek.c, I changed the equality test so we would end up in ALC888 section... result was I got an extra volume control on mixer for BEEP. previously did not hear beeps when hitting down in terminal. BEEP is in headphones or line out. still not on speakers. aplay -l listed ALC888 too but codec#0 still showed ALC1200... I dont know the flow of information changes in ALSA to change this codec... I undid the equality test change and now its back to original realtek patch, recompiled reinstalled... added model=generic, to asound.state, this gave me more controls IIRC.. downloaded codecgraph utility, result: http://img20.imageshack.us/img20/8692/codec0.png I dont know how these codecgraphs work, but 4 jacks are right! the internal speakers appear twice?? how can one rewire these, or enable assuming dotted is disabled, does every amplifier triangle correspond to a volume control? is there a direct way to make changes? dmesg |grep hda: [ 16.172695] hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...
