Hi Takashi,
Since I started using Linux on a MBA2,1 I never had sound working. recently searching for some solution to get sound working I saw that some users had sound with 3.2.x kernels and reported it stopped working somewhere between 3.2 and 3.4.
Thus I tried bisecting this and found two steps of losing sound support, a first one being losing sound output on built-in speaker, a second point where sound through headphone jack stopped working.
Even with 3.2 non of the mute options is working (I did not try recording via build-in microphone)
...
Attached is the output of `alsa-info --with-devices` under current 3.12.2 kernel and under 3.2.53.
As this all seems related to quirks being replaced with auto-parsing. Trying to revert the commits on top of 3.12.x looks unworkable.
Is there some extra data I should try to provide or a workaround/fix I could try out? I'm booting in EFI mode using EFI stub (did backport it from 3.3 to 3.2 for bisecting/testing 3.2).
You seem to be passing model=3stack, and this must break things. To be sure, try sound.git tree for-linus branch without any options. git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git
I tried your branch (with merged rc2 from Linus) and there is still no sound. (took some time to test as kernel freezes during boot somewhere in nouveau, thus me merging in rc2 in the hope of a fix for that)
Thanks. Could you try the patch below?
Wow, that patch does a marvelous job!
Controls listed by alsamixer seem to all work the way they are intended, MASTER affects both headphone jack and built-in speaker, muting works per-channel as does volume.
Even the toggle "Headphone/mic jack" seems to perform the operation indicated by its name (though I did not try recording yet).
So the patch is (Reported-and-)Tested-by: Bruno Prémont bonbons@linux-vserver.org
Thanks for your quick response and looking into this!
A rather borderline question/observation: When plugging in headphone and the jack is configured as headphone built-in speaker gets muted (seems reasonable default, hardware triggered). Is it possible to have that auto-muting reported in mixer and possibly overridden via mixer if wanted (possibly via mute-speaker-if-headphone-plugged option)?
Bruno
