Your suggestion reminds me of another bug on another Vaio Z model but with a different codec. On that machine, the speaker output must come from the first DAC. Otherwise silences. Julien's machine might have a similar restriction.

The patch below will change the DAC assignment order. Give it a try instead of previous ones.

Unfortunately, this doesn't help at all: with that patch I've a bunch of different noises following what I mute/unmute. And muting/unmuting the "Beep" toggles a different noise, but I cannot find the silence back. :(
