[alsa-devel] [patch 0/6] sound azt3328: fix bugs, improve codec layering, speedup
by andi＠lisas.de 02 Jan '11

02 Jan '11

This azt3328 PCI sound driver patch series contains some remaining cleanup, several fixes and some nice improvements. Tested and checkpatch.pl'ed on 2.6.37-rc6. Despite improved functionality the compiled binary is now some 300 bytes smaller (dito for source). Will be one of the last updates to azt3328, I promise ;) (I've got some other interesting work for more widespread cards) Thanks! Andreas Mohr

The soundcard Realtek ALC888 needs a fix when used with acer-aspire-4930g. Main volume is not initialized. Please take a look here https://bugtrack.alsa-project.org/alsa-bug/view.php?id=5176. I wrote a patch to solve this problem on my laptop. And it works like a charm.Thanks in advance.

[alsa-devel] ASoC updates for 2.6.37
by Mark Brown 02 Jan '11

02 Jan '11

The following changes since commit 862af8adbe6b9ccb7c00c13717b1f92465f79aa2: ASoC: Fix bias power down of non-DAPM codec (2010-12-13 16:47:48 +0000) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git for-2.6.37 This is very late for such a big set of changes, but unfortunately Lars-Peter only reported them just before Christmas. Most of the changes are small and easy to verify by hand, the big one is the WM8753 which has had the benefit of testing from Lars-Peter and which consists mostly of replacing the custom wm8753 write function with the generic snd_soc_write() and so can be relatively easily verified by eye. In case you don't want to send these on to Linus I've also marked them as CC to stable so they'll go into the stable release when that goes out.

[alsa-devel] CONFIG_SND_HDA_INTEL regression on 2.6.37-rc3 - no audio
by Luis R. Rodriguez 02 Jan '11

I just booted 2.6.37-rc3 and noticed my sound with CONFIG_SND_HDA_INTEL stopped working, I get no audio at all. Is this a known regression? I can bisect if not. $ lsmod| grep snd snd_hda_codec_analog 79955 1 snd_hda_intel 25446 3 snd_hda_codec 101539 2 snd_hda_codec_analog,snd_hda_intel snd_hwdep 6546 1 snd_hda_codec snd_pcm 88139 3 snd_hda_intel,snd_hda_codec snd_seq_midi 5900 0 snd_rawmidi 21916 1 snd_seq_midi snd_seq_midi_event 7291 1 snd_seq_midi snd_seq 56979 2 snd_seq_midi,snd_seq_midi_event snd_timer 23148 2 snd_pcm,snd_seq snd_seq_device 6912 3 snd_seq_midi,snd_rawmidi,snd_seq snd 63192 15 snd_hda_codec_analog,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,thinkpad_acpi,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 1240 1 snd snd_page_alloc 8716 2 snd_hda_intel,snd_pcm Luis
