[alsa-devel] [PATCH] hdmi - merge common code for intelhdmi and nvhdmi
by Wu Fengguang 08 Mar '10

08 Mar '10

Create patch_hdmi.c to hold common code from intelhdmi and nvhdmi. For now the patch_hdmi.c file is simply included by patch_intelhdmi.c and patch_nvhdmi.c, and does not represent a real codec. There are no behavior changes to intelhdmi. However nvhdmi made several changes when copying code out of intelhdmi, which are all reverted in this patch. Wei Ni confirmed that the reverted code actually works fine.

[alsa-devel] 2.6.30-rc8 skipping regression also affects cmipci
by Frédéric Brière 07 Mar '10

07 Mar '10

Hi everybody, I was only recently able to upgrade from 2.6.26 to 2.6.32 (long story). In so doing, I noticed infrequent occurrences of audio skipping, which I managed to bisect down to c87d973. It would appear that this commit also affects cmipci (CMI8738), albeit not as badly as it did for intel8x0. (I guess I'm the only person left on Earth still using a stand-alone PCI sound card, which is why this was never reported. <g>) Here's a sample log output after turning xrun debugging on: [ 171.555860] PCM: hw_ptr skipping!

[alsa-devel] usb-audio code refactoring, more v2 support [resend]
by Daniel Mack 05 Mar '10

05 Mar '10

This is a rebased version of the usb-audio cleanup patch set. On top of what's already been posted, there is one more fix to support sample rate configuration, and one bugfix. Commit 864c11080 was also ported over. And Clemens' latest patches are also included. With these patches applied, I can stream audio on a class v2 device. At least for awhile, then I get CRC errors in DATA0 packets. But that's a different issue. What's not yet done is all the feature unit parsing, mixers etc. Daniel [PATCH 1/8] ALSA: usb-audio: move ua101 driver [PATCH 2/8] ALSA: usb-audio: header file cleanups [PATCH 3/8] ALSA: usb-audio: refactor code [PATCH 4/8] ALSA: usb-audio: rename substream format field to altset_idx [PATCH 5/8] ALSA: usb-audio: use a format bitmask per alternate setting [PATCH 6/8] ALSA: usb-audio: support multiple formats with audio class v2 devices [PATCH 7/8] ALSA: usb-audio: add support for samplerate setting on v2 devices [PATCH 8/8] usb/audio.h: Fix field order

[alsa-devel] [PATCH 4/8] ALSA: usb-audio: rename substream format field to altset_idx
by Daniel Mack 05 Mar '10

From: Clemens Ladisch <clemens(a)ladisch.de> The snd_usb_substream::format field actually contains the index of the current alternate setting, so rename it to altset_idx to avoid confusion.
