alsa-lib 1.0.20 running alsamixer -a basic gives: ALSA lib python.c:991:(alsa_mixer_simple_finit) Unable to find python module '/usr/lib/alsa-lib/smixer/python/main.py' How do I build smixer/python/main.py ? Elimar -- On the keyboard of life you have always to keep a finger at the escape key;-)

[alsa-devel] [BUG] NULL pointer dereference in patch_sigmatel.c
by Ozan Çağlayan 10 Aug '09

10 Aug '09

Hi, One of our users is having a NULL ptr dereference upon loading the snd_hda_intel module with 20090624's snapshot. There's only one commit after that date in patch_sigmatel.c so I didn't tell him to try with the latest snapshot but if you think that the bug may be related to another part of the ALSA codebase, I can make him try the latest snapshot. I'm attaching the alsa-info output on a working system with 1.0.18a. The kernel version in subject is 2.6.25.20. Thanks, Ozan ------------------------ First the BUG's trace: ------------------------ BUG: unable to handle kernel NULL pointer dereference at 00000074 IP: [<f8cdb83a>]

[alsa-devel] [PATCH 1/2] ASoC: DaVinci: McASP driver enhacements
by Chaithrika U S 10 Aug '09

10 Aug '09

On DA830/OMAPL137 SoC, the McASP peripheral has internal FIFO support. It provides additional data buffering. It also provides tolerance to vairiation in host/DMA controller response times. The read and write FIFO sizes are 256 bytes each. If FIFO is enabled, the DMA events from McASP are sent to the FIFO which inturn sends DMA requests to the host CPU according to the thresholds programmed. More details of the FIFO operation can be found at http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber= sprufm1&fileType=pdf This patch adds support for FIFO configuration.The platform member has a version field which differentiates the McASP on different SoCs. The patch also adds another DAI format to the driver.

[alsa-devel] ASoC: PCM formats for AC97
by Jon Smirl 09 Aug '09

09 Aug '09

Tell me if this is right and I'll do a patch.... ----------------------------------------------------------- The current mpc5200 code has: static const struct snd_pcm_hardware psc_dma_hardware = { .formats = SNDRV_PCM_FMTBIT_S8 | SNDRV_PCM_FMTBIT_S16_BE | SNDRV_PCM_FMTBIT_S24_BE | SNDRV_PCM_FMTBIT_S32_BE, struct snd_soc_dai psc_ac97_dai[] = { { .playback = { .formats = SNDRV_PCM_FMTBIT_S32_BE, I think I have this backwards, the ac97 driver can take 8/16/24/32 it's the Bestcomm program that doesn't know about anything except 32b. So if we wrote new Bestcomm programs that expanded bytes from memory out into 32b DMA register writes, we could support 8/16b formats. The correct formats would be: static const struct snd_pcm_hardware psc_dma_hardware = { .formats = SNDRV_PCM_FMTBIT_S32_BE, struct snd_soc_dai psc_ac97_dai[] = { { .playback = { .formats = SNDRV_PCM_FMTBIT_S8 | SNDRV_PCM_FMTBIT_S16_BE | SNDRV_PCM_FMTBIT_S24_BE | SNDRV_PCM_FMTBIT_S32_BE, After implementing new Bestcomm programs.... static const struct snd_pcm_hardware psc_dma_hardware = { .formats = SNDRV_PCM_FMTBIT_S8 | SNDRV_PCM_FMTBIT_S16_BE | SNDRV_PCM_FMTBIT_S24_BE | SNDRV_PCM_FMTBIT_S32_BE, ----------------------------------------------------------- A related issue in soc-dai.h: #define SND_SOC_STD_AC97_FMTS (SNDRV_PCM_FMTBIT_S16_LE |\ SNDRV_PCM_FMTBIT_S32_LE |\ SNDRV_PCM_FMTBIT_S32_BE) shouldn't this be #define SND_SOC_STD_AC97_FMTS (SNDRV_PCM_FMTBIT_S16 |\ SNDRV_PCM_FMTBIT_S32) The first form says the AC97 hardware can take both endians, but it doesn't take both endians it takes the endian matching the machine it is attached to. Don't the standard AC97 formats also include 8 and 24b? -- Jon Smirl jonsmirl(a)gmail.com

[alsa-devel] Testers wanted: New SB X-Fi driver
by Frashman 09 Aug '09

09 Aug '09

Hi Takashi, first of all, thank you for developing this driver. I tested it today. It works, so far. But two annoying things. As you mentioned, I got problems, if the onboard sound modules are loaded. Then i get no sound out auf my xfi. If I disable the loading of snd-hda-intel modules while booting, then it works. The second problem is, that SIDE and SURROUND connectors are interchanged. I'm absolutly sure, it works fine under windows and the connector colors are also correct. If I run speaker-test -c8 the SIDE Speakers sounds come out of my REAR (SURROUND) Speakers, while nothing is coming out of my rear speakers, if i'm using speaker-test -c6 Here lspci: $ lspci 00:00.0 Host bridge: ATI Technologies Inc RD780 Northbridge only dual slot PCI-e_GFX and HT1 K8 part 00:02.0 PCI bridge: ATI Technologies Inc RD790 PCI to PCI bridge (external gfx0 port A) 00:04.0 PCI bridge: ATI Technologies Inc RD790 PCI to PCI bridge (PCI express gpp port A) 00:0a.0 PCI bridge: ATI Technologies Inc RD790 PCI to PCI bridge (PCI express gpp port F) 00:12.0 SATA controller: ATI Technologies Inc SB600 Non-Raid-5 SATA 00:13.0 USB Controller: ATI Technologies Inc SB600 USB (OHCI0) 00:13.1 USB Controller: ATI Technologies Inc SB600 USB (OHCI1) 00:13.2 USB Controller: ATI Technologies Inc SB600 USB (OHCI2) 00:13.3 USB Controller: ATI Technologies Inc SB600 USB (OHCI3) 00:13.4 USB Controller: ATI Technologies Inc SB600 USB (OHCI4) 00:13.5 USB Controller: ATI Technologies Inc SB600 USB Controller (EHCI) 00:14.0 SMBus: ATI Technologies Inc SBx00 SMBus Controller (rev 14) 00:14.1 IDE interface: ATI Technologies Inc SB600 IDE 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) 00:14.3 ISA bridge: ATI Technologies Inc SB600 PCI to LPC Bridge 00:14.4 PCI bridge: ATI Technologies Inc SBx00 PCI to PCI Bridge 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:00.0 VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4850] 01:00.1 Audio device: ATI Technologies Inc HD48x0 audio 02:00.0 Audio device: Creative Labs X-Fi Titanium series [EMU20k2] (rev 03) 03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

[alsa-devel] Auzentech X-Fi Prelude with alsa drivers

Dear sirs, I've got a Auzentech X-Fi Prelude and I installed the alsa unstable snapshot drivers. Stereo sound for my headphones and ditital output are working fine but my microphone isn't recording anything. I was checking the mixer settings but i wasn't able to find something wrong. Are the x-fi drivers just not designed to fit with the Auzentech card or do i have a local configuration problem? The output of alsa-info.sh script is attached.

[alsa-devel] Problems with gain controls
by James Courtier-Dutton 09 Aug '09

09 Aug '09

Hi, Does anyone know how to disable pulse from making any changes to the alsa hardware mixer controls? I would prefer pulse to use software gain controls, and not touch the alsamixer levels. pulse seems to do a very bizarre thing. The single master gain control within pulse changes both the alsamixer PCM and Master controls. Kind Regards James
