Subject: [SOUND] SBx00 sound card using snd_hda_codec_analog auto mutes

On my laptop, the sound card auto mutes some seconds after i enable it.
And play a audio file can't make sound. This is not a powersave feature,
because i haven't enable it. I guess it's a driver problem. It occurs
since 2.6.36.X. Please help.

Card: Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)
Module: snd_hda_codec_analog, snd_hda_intel

The possible useful information are followed.
