I'm marking this as confirmed based on similar behavior on my dv7 and a workaround that could form the basis for a fix. The workaround is to add the following line to /etc/modprobe.d/alsa-base:
options snd-hda-intel enable_msi=1 I write "workaround, not fix", for at least two reasons: 1. The user should not have to do this, and, more importantly, 2. After a recent round of updates, this file disappeared for me, but it's entire contents were copied to /etc/modprobe.d/alsa-base.conf - and the problem returned! When I did "cp -p /etc/modprobe/alsa-base.conf /etc/modprobe/alsa-base" and rebooted, the problem went away, sound was good again. The fix would be to have this option set by default for the dv7 series.
