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

[Øyvind Stegard]

I'm currently running snd-hda-intel module with options "position_fix=1
bdl_pos_adj=0". This stops "[hd-audio0]" from showing up in top, but
audio still crackles when scrolling in Firefox (for instance) after
having used the desktop session for a while (more windows and apps open
=> more graphical resource usage). So in-kernel audio driver is badly
affected by graphical operations, so much that it probably voids any
effect of setting higher priority on pulseaudio user-space process...
