Comment 17 for bug 1019693

I seem to have found a workaround - disabling message signalled interrupts for snd_hda_intel. I guess they are b0rked for this driver - were they switched on recently? I recall that the driver started stuttering only after a kernel "upgrade" that was released after Precise stable was released.

Edit /etc/modprobe.d/alsa-base.conf and append "enable_msi=0" to the "options snd-hda-intel" line (should be near the end).

Chrome flash video was completely unusable prior to this for stuttering and skipping, but seems quite solid now.
