[Bug 28443] Re: no sound Intel HDA (ICH6) and ALC260 (or ALC880) mixer; no errors

[Václav Šmilauer]

The Acer portion of the bug seems to be resolved, though. For the Vaio, try recompiling ALSA driver with debug enabled and use the 'test' model to find out routing on the ALC chip (see ALSA bugs referenced above for howto; the 'test' model is useful if Vaio doesn't use GPIO registers, as Acers do).

I recommend using the ALSA bugtrack, the devs there may help you.

Also, consider opening a separate bugreport specifically for Vaio, perhaps renaming this one to have Acer in the title.
