Public bug reported:
I am testing on raring. To reproduce try playing a you tube video, the audio
will go in and out. In addition playing back music in rhythmbox will also
exhibit the same problems.
When looking at dmesg I see the following lines:
[ 1653.495497] hda-intel: spurious response 0x40:0x3, last cmd=0x30270503
[ 1653.495498] hda-intel: spurious response 0x4011:0x3, last cmd=0x30270503
[ 1653.495500] hda-intel: spurious response 0x0:0x3, last cmd=0x30270503
[ 1653.495501] hda-intel: spurious response 0x5:0x3, last cmd=0x30270503
[ 1654.591127] hda_intel: azx_get_response timeout, switching to single_cmd
mode: last cmd=0x301f0500
Eventually after this the audio cuts out complete and nothing can be
heard. Not sure if this is a pulseaudio bug or an intel driver bug.
