[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

Re: [alsa-devel] [PATCH 2/2] [v2] powerpc/85xx: add DIU support to the Freecale P1022DS reference board
by Timur Tabi 14 Oct '10

14 Oct '10

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. You can grab the patch from http://patchwork.ozlabs.org/patch/67095/ On Thu, Oct 7, 2010 at 2:36 PM, Timur Tabi <timur(a)freescale.com> wrote: > The Freescale P1022DS has an on-chip video controller called the DIU, and a > driver for this device already exists.

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.
