[alsa-devel] [PATCH 0/5] snd-usb endpoint logic rework, version 3
by Daniel Mack 19 Dec '11

19 Dec '11

This is the 3rd round, and I didn't mark it RFC anymore as Clemens and Takashi agreed on the way of implementation in general. So in comparison to the last version, this round incorporates some spinlock fixes, a lot less debugging output and my S-o-b lines. Please test this extensively with different sound cards. I didn't experience a single problem over the last hours of testing, but the more testing the better. Thanks, Daniel Daniel Mack (5): ALSA: snd-usb: add snd_usb_audio-wide mutex ALSA: snd-usb: implement new endpoint streaming model ALSA: snd-usb: switch over to new endpoint streaming logic ALSA: snd-usb: remove old streaming logic ALSA: snd-usb: add support for implicit feedback sound/usb/card.c | 8 +- sound/usb/card.h | 65 +++ sound/usb/endpoint.c | 1427 +++++++++++++++++++++++++------------------------- sound/usb/endpoint.h | 31 +- sound/usb/pcm.c | 428 +++++++++++++--- sound/usb/stream.c | 31 +- sound/usb/usbaudio.h | 2 + 7 files changed, 1191 insertions(+), 801 deletions(-) -- 1.7.5.4

[alsa-devel] [PATCH 0/5] RFC v2 for snd-usb endpoint logic rework
by Daniel Mack 18 Dec '11

18 Dec '11

This is v2 of the patch bulk I posted some weeks ago, which incoporates the points that were discussed. Thanks to everyone who commented and helped with sugesstions. This version work really well here, but as last time, it needs a lot more testing. What's still missing are some cleanups and more documentation, I'll do that once the acutal content is agreed upon. Patches should apply cleanly to the latest mainline git + Takashi's sound tree. Thanks for any feedback for this next round, Daniel Daniel Mack (5): ALSA: snd-usb: add snd_usb_audio-wide mutex ALSA: snd-usb: implement new endpoint streaming model ALSA: snd-usb: switch over to new endpoint streaming logic ALSA: snd-usb: remove old streaming logic ALSA: snd-usb: add support for implicit feedback sound/usb/card.c | 8 +- sound/usb/card.h | 65 +++ sound/usb/endpoint.c | 1434 +++++++++++++++++++++++++------------------------- sound/usb/endpoint.h | 31 +- sound/usb/pcm.c | 444 +++++++++++++--- sound/usb/stream.c | 31 +- sound/usb/usbaudio.h | 2 + 7 files changed, 1214 insertions(+), 801 deletions(-) -- 1.7.5.4

This serial converts some pxa machine drivers to use use snd_soc_register_card(). Note: I don't have these hardware, so I appreciate if someone can test these patches.

[alsa-devel] Alsa-lib version info
by Alan Horstmann 16 Dec '11

16 Dec '11

Hi, I have read in the docs about snd_asoundlib_version() to get a version string, but is there a way to get the SND_LIB_VERSION number from a runtime Alsa-lib, rather than from the header included at application build time, or would it have to be constructed from the string? Thanks Alan

[alsa-devel] Jabra SPEAK 410 USB - no audio playback

I got one of these rather nice USB conference phones. It works fine with Windows/Mac. ALSA gives the following errors: [336517.162535] usb 1-1.1: SerialNumber: 0023781E0530x010100 [336517.172419] ALSA sound/usb/stream.c:176 10:1:1 : no or invalid class specific endpoint descriptor [336517.177029] ALSA sound/usb/stream.c:176 10:2:1 : no or invalid class specific endpoint descriptor [336517.183248] ALSA sound/usb/mixer.c:795 2:0: cannot get min/max values for control 2 (id 2) [336517.183350] ALSA sound/usb/mixer.c:795 5:0: cannot get min/max values for control 2 (id 5) [336517.236151] input: Jabra SPEAK 410 USB as /devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1/1-1.1:1.3/input/input13 The microphone and other features are fine, but there is no playback. I hope I've attached all possible details about this device, but if there is anything I've missed out, please let me know.

[alsa-devel] [PATCH v4 0/5] Support for OMAP4 Digital Microphone interface
by Peter Ujfalusi 16 Dec '11

16 Dec '11

Hello, The following series will add support for OMAP4 DMIC interface, and enable them on sdp4430/Blaze boards. Changes since v3: - dmic clk divider selection moved to hw_params phase to allow fixed rate configuration from machine driver init. Changes since v2: - Use module_platform_driver - convert to use devm_ - Add clk_id for the output clock - Extend the comment to explain why the driven can change the divider for 192KHz sampling rate. Changes since v1: - 192KHz rate support fixed (need to use different divider) - Hold reference for dmic_fclk over the lifetime of the driver - Removed the clkdiv callback, and replaced with frequency based configuration for the external components (dmic frequency) Regards, Peter --- Peter Ujfalusi (5): OMAP4: hwmod: Add names for DMIC memory address space ASoC: OMAP4: omap-dmic: Initial support for OMAP DMIC OMAP4: devices: Register OMAP4 DMIC platform device OMAP4: board-4430sdp: Register platform device for digimic codec ASoC: sdp4430: Add support for digital microphones arch/arm/mach-omap2/board-4430sdp.c | 6 + arch/arm/mach-omap2/devices.c | 22 ++ arch/arm/mach-omap2/omap_hwmod_44xx_data.c | 2 + sound/soc/omap/Kconfig | 5 + sound/soc/omap/Makefile | 2 + sound/soc/omap/omap-dmic.c | 549 ++++++++++++++++++++++++++++ sound/soc/omap/omap-dmic.h | 69 ++++ sound/soc/omap/sdp4430.c | 85 ++++- 8 files changed, 729 insertions(+), 11 deletions(-) create mode 100644 sound/soc/omap/omap-dmic.c create mode 100644 sound/soc/omap/omap-dmic.h -- 1.7.8.rc3

[alsa-devel] [PATCH] Fix compile error in sound/soc/mid-x86/sst_platform.c
by Joerg Roedel 16 Dec '11

16 Dec '11

(again with mailing lists on Cc, sorry) Hi, I tested current linux-next against my iommu-configs and found a compile error in sound/soc/mid-x86/sst_platform.c. The variable ret_val in the sst_platform_open() function is used but not declared. Attached patch fixes this.
