[alsa-devel] Recent code changes for HD-audio on HG repo

As you said, the patch didn't solve the problem.
To test audio I used this simple command:

aplay < /bin/bash

but if there is no audio output for a while, executing it produces no noise.
When I said the sound goes mute, I meant there is no sound, not that some
audio channel is muted.

If I set the power_save_controller=0 module option the sound works always, 
so these are the details of my hardware:
