[ 1653.495497] hda-intel: spurious response 0x40:0x3, last cmd=0x30270503 is definitely a driver bug.
Is this a regression from quantal or did you see the same behaviour in previous Ubuntu releases? ** Package changed: pulseaudio (Ubuntu) => alsa-driver (Ubuntu) ** Summary changed: - hda-intel: spurious response - audio dropping out during playback + [ThinkPad T420] hda-intel: spurious response - audio dropping out during playback -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1088957 Title: [ThinkPad T420] hda-intel: spurious response - audio dropping out during playback Status in “alsa-driver” package in Ubuntu: New Bug description: 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.
