Subject: 2.5 Interactivity & XMMS audio skipping

Hi,

While playing with 2.5.65 and 2.5.64-mm8 I've been able
to reproduce audio skipping with XMMS while moving a
large window on my KDE desktop (no other CPU-bound
process except "kdeinit" waking up periodically to steal
1-3% CPU). What's really curious is that after some time,
the scheduler seems to adjust in such a way that I can't
reproduce the audio skip anymore easily.

In 2.5.64-mm8 it's easier to avoid sound skipping by
adjusting "max_timeslice" to a 25 or lower. However, on
2.5.65, I must wait for the scheduler to do its magic. After
that time, dragging the window over the screen (either
very fast or very slowly) does not always reproduce the
audio skip.

Thanks!

Felipe

I do not have skipping, but if I play short samples eg. less than two
seconds, I get same sample repeated abot 7-8 times. Longer ones play OK
except last sec or two, than last two seconds which are repeated same way as
short samples.

This is happening since 2.5.59, but not in 2.5.52. 2.5.53-2.5.58 not tested.
