(Get the code!)
Just did a fresh install of Quantal and this issue is still present, so thought I'd update the bug.
I am not seeing the "hpet increasing min_delta_ns" from the referenced bug, so while perhaps related it seems to be a different issue.
To reproduce:
speaker-test -t sine -f 100
There will be intermittent periods of distortion in the left (0) channel, that sounds like a sort of mechanical mincing / comb filter. I could provide an audio sample if that would help.
The "nohz=off" boot param workaround still works.
