Some time ago, it was already discussed here that Rhythmbox would easily
cause audio skipping when running with the CFS scheduler (http://
bhhdoa.org.au/pipermail/ck/2007-June/007886.html). It was said to be a
Rhythmbox problem, for which someone needed to open a bug report. Well, I
just did this, but the developer says he cannot reproduce this, and denies
that Rhythmbox is making any X calls in its audio playback thread, so this
bug is blocked for the moment.
It seems that there are people who know better what is wrong exactly. Can
somebody give some more details about what Rhythmbox is doing wrong,
either here, either in the bug ticket?
could you first check whether CFS v20.3:
is it still showing the same symptoms with rhythmbox? If yes, what kind
of load of yours is typically causing the Rhythmbox skipping? x11perf?
