Hi,

The problem persists, has always persisted, and any message I've posted
indicating anything else is to be ignored ;)

Heavy disk I/O seems to be a trigger for the problem. I always hear the
screwups, but i.e. when building mozilla or openoffice (during the
extract phase with heavy I/O), sound almost slows down to a complete
stop, stutters and hicks and cracks all the time - to a point where the
music is almost impossible to even identify anymore.

I've tried forcing my soundcard (C-Media and SB Live!) to use a 'free'
IRQ, i.e. no IRQ sharing - but this doesn't help.
One good way to reproduce atleast the audible result of the problem is
to load a kernel module (even something like samba support) while sound
is playing. Try and thou shall hear.

Suffice to say, if FreeBSD 5.x goes -STABLE with this issue still
present it will be a major 'turn off' for many, notwithstanding the
argument that FreeBSD is not for desktop use anyway :P


Best regards,
/Eirik
