BTW, does my patch fix the problem when you load without model=auto?
I have just booted to the rc2 with the patch (https://lkml.org/lkml/2011/6/9/25) and it looks it didn't solve the problem. Playback works only from speakers when headphones are not plugged in - no sound if plugged in.
So, the auto-mute now works but now the headphone doesn't work. Weird... Maybe the same reason the speaker doesn't work with auto-mode. I saw that the only one converter keeps the stream in your alsa-info.sh output although multiple converters (0x02, 0x03, 0x06) should be used simultaneously.
See alsa-info.txt-fresh-boot. Same thing happens if I modprobe -r snd-hda-intel and then load it again (without any parameters).
If yes, does the problem appear with it? I.e. is the silence problem specific to model=auto or not?
If I try to modproble with model=auto I get headphones working but not output from speakers. Have a look at alsa-info.txt-modprobe_auto.
For testing, just copy 2.6.39/sound/pci/*.[ch] into 3.0 tree and rebuild.
OK, I git checkout v2.6.39 -- sound/pci/*.[ch] (see the patch bellow for reference). I have kept the earlier patch.
Gah, sorry, a wrong path. It must be sound/pci/hda/*.[ch]. Also, please remove my previous patch. It's irrelevant with 2.6.39 although it should be harmless.
Regarding the missing speaker-output on model=auto: I found the culprit. The current auto-parser for ALC262 doesn't probe the secondary DAC. So, it's a logical bug. I'm going to fix this for 3.1. From now on, let's keep tracking only the issue without model option.
thanks,
