[Bug 571770] Re: Thread [hd-audio0] consuming excessive amounts of CPU during audio playback

[Øyvind Stegard]

Tried snd-hda-intel option "enable_msi=1", since I figured it might be
some IRQ issue. That didn't help.

So I noticed CPU0 was handling all interrupts occuring on my system (via
/proc/interrupts) for radeon and hda-intel modules. I altered the IRQ
affinity for hda-intel, so it would be handled on the other CPU, but
that did not help on the audio crackling either.

So it seems I'm properly stuck for now, unless someone can come up with
some other advice. Try newer kernel, perhaps ? Mainline PPA ?
