As pulseaudio server use SND_PCM_NO_AUTO_CHANNEL which diable channel conversion, this left channel device only work with other alsa applications except pulseaudio when your sound card does not support mono. http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/?id=ff4af902cf4ac0… the solution is to change the mixing in pulseaudio by using left channel for this mic and those stereo mic with inverted phase , and average for mono playback device . stereo mic and line-in how about the 4 channel mic? > > -- Tanu > > > On Fri, 2012-08-10 at 14:25 +0300, Tanu Kaskinen wrote: > > Hi, > > > > I'm writing UCM configuration for RX-51 (Nokia N900), and I have a > > problem: "hw:RX51" can't be opened in mono mode, but there's only one > > integrated mono microphone, and its audio is routed to the left input > > channel.

[alsa-devel] [PATCH 0/3] ALSA: snd-usb: Regression fixes for 3.5
by Daniel Mack 04 Sep '12

04 Sep '12

Here are 3 more regression fixes for snd-usb in 3.5. It's annoying they haven't been found earlier, but at least we're now back to the streaming quality we had before the streaming refactoring. Anyone with a USB device, please give it a quick shot at least.

[alsa-devel] [PATCH v3 0/3] introduce device_buffer
by Vinod Koul 04 Sep '12

04 Sep '12

Old wine in a new bottle with added flavour now. Based on our discussions in LPC, now we will report the combined delay value as sum of the buffering done in driver and hardware. This is used to report delay Additionally we tell pcm what is buffer in device/driver, this is used to check for error calulcations Vinod Koul (3): ALSA: pcm - introduce device_buffer ASoC: add device_buffer in asoc ASoC: mid-x86 - implement buffer query in sst_platform driver include/sound/pcm.h | 1 + include/sound/soc-dai.h | 6 ++++++ include/sound/soc.h | 6 ++++++ sound/core/pcm_lib.c | 10 +++++++++- sound/soc/mid-x86/sst_platform.c | 23 +++++++++++++++++++++++ sound/soc/mid-x86/sst_platform.h | 4 +++- sound/soc/soc-pcm.c | 13 ++++++++++++- 7 files changed, 60 insertions(+), 3 deletions(-) -- 1.7.9.5

[alsa-devel] [PATCH 0/3] ALSA: Add DSP firmware loader
by Ian Minett 04 Sep '12

04 Sep '12

From: Ian Minett <ian_minett(a)creativelabs.com> Hi Takashi, Thanks for the recent code samples, they were very useful. We've built on them to produce this latest patchset, incorporating the updates you provided to add the loader functions, and doing a minimal update to the CA0132 codec to use the new ops to perform the firmware transfer. Please let us know if any tweaks are needed to the update. Thanks, - Ian Signed-off-by: Ian Minett <ian_minett(a)creativelabs.com> --- 1: - memalloc.h - pcm.h - pcm_memory.c - sgbuf.c Include Takashi's updates: Make snd_sgbuf_get_{ptr|addr}() available for non-SG cases. Passing struct snd_dma_buffer pointer instead, so that they work no matter whether real SG buffer is used or not. 2: - hda_intel.c - hda_codec.h Include Takashi's updates: Pass DMA buffer pointers in calls to setup_bdle(). Add new callback routines to controller to handle loading firmware binaries. Add new switch to Kconfig to enable DSP firmware loader. 3: - patch_ca0132.c - ca0132_regs.h Add support for DSP firmware transfer to CA0132 codec: Add transfer handler functions. Call the new snd_hda_codec_load_dsp_xxx loader ops to control download. Add chip access routines.

[alsa-devel] [PATCH] ALSA: hda - Fix runtime PM accounting
by Takashi Iwai 02 Sep '12

02 Sep '12

The flag codec->d3_clk_stop_ok isn't always set when the codec is powered off. If it's not set, the controller driver doesn't change the runtime PM count. This causes an unblanced accounting when multiple codecs are present. Usually, the first codec is powered down with CLK_STOP_OK=0, then the next codec with CLK_STOP_OK=1. At this moment, the first codec is changed also to CLK_STOP_OK=1, but this isn't informed to the controller. Thus it still thinks as if one codec is active. For fixing this issue, move the check of CLK_STOP_OK bit at the runtime suspend time, and simple up/down by the codec power save in azx_power_notifier(). For CLK_STOP_OK bit checks of all codecs, a new helper function is introduced. With this change, d3_clk_stop_ok field is no longer referred, thus removed. Also, d3_clk_stop bit field is moved to a place where more efficiently packed. Signed-off-by: Takashi Iwai <tiwai(a)suse.de> --- I faced this issue while I'm checking the pm issue.

[alsa-devel] [PATCH] ASoC: samsung dma - Don't indicate support for pause/resume.
by Dylan Reid 01 Sep '12

01 Sep '12

The pause and resume operations indicate that the stream can be un-paused/resumed from the exact location they were paused/suspended. This is not true for this driver, the pause and suspend triggers share the same code path with stop, they flush all pending DMA transfers. This drops all pending samples. The pause_release/resume triggers are the same as start, except that prepare won't be called beforehand, nothing will be enqueued to the DMA engine and nothing will happen (no audio). Removing the pause flag will let apps know that it isn't supported. Removing the resume flag will cause user space to call prepare and start instead of resume, so audio will continue playing when the system wakes up. Before removing the pause and resume flags, I tested this on an exynos 5250, using 'aplay -i'. Pause/un-pause leads to silence followed by a write error. Suspend/resume testing led to the same result. Removing the two flags fixes suspend/resume (since snd_pcm_prepare is called again). And leads to a proper reporting of pause not supported.

[alsa-devel] [PATCH 6/9] ARM: OMAP: Move gpio.h to include/linux/platform_data
by Tony Lindgren 01 Sep '12

01 Sep '12

This way we can remove includes of plat/gpio.h which won't work with the single zImage support. Note that we also remove the cpu_class_is_omap2() check in gpio-omap.c as the drivers should not call it as we need to make it local to arch/arm/mach-omap2 for single zImage support. While at it, arrange the related includes in the standard way.

[alsa-devel] [PATCH 0/3] introduce device_buffer
by Vinod Koul 31 Aug '12

Old wine ina new bottle, so here is the second attempt for adding the notion of how devices (in my case a DSP) can buffer data and that can be used by sound core Vinod Koul (3): ALSA: pcm - introduce device_buffer ASoC: add device_buffer in asoc ASoC: mid-x86 - implement buffer query in sst_platform driver include/sound/pcm.h | 1 + include/sound/soc-dai.h | 6 ++++++ include/sound/soc.h | 7 ++++++- sound/core/pcm_lib.c | 14 +++++++++++--- sound/core/pcm_native.c | 6 +++--- sound/soc/mid-x86/sst_platform.c | 23 +++++++++++++++++++++++ sound/soc/mid-x86/sst_platform.h | 4 +++- sound/soc/soc-pcm.c | 13 +++++++++++++ 8 files changed, 66 insertions(+), 8 deletions(-) -- 1.7.9.5

Possible this breakage may be resolved by run > "make distclean" before "make all". Sorry! It's actually a bug of the build system.. I just fixed it. Thanks, Fengguang
