I've also seen this (or something simular). I've sent bug report to
freebsd-multimedia@FreeBSD.ORG some time ago.
If anybody intersted I'll repeat it here:
=========>my email to freebsd-multimedia@FreeBSD.ORG here>======
I've seen twice my Aureal Vortex 8810 card stops working after several
days of uptime. Both times I've seen it after having XMMS playing mp3
files from NFS share for several days (my PC at work always up and I'm
listen misic via headphones - so I often leave XMMS playing for
several days). XMMS plays mp3s via esd. So I belive sound stop working
if sound device /dev/dsp is keeped opened for several days.
Applications that use sound occasionally find that /dev/dsp is busy.
For example:
$ esd
/dev/dsp: Device busy
I'm sure that nobody holds this device opened - I've checked it with
lsof.
/dev/dsp0.2, /dev/dsp0.3, /dev/dsp0.4 also are busy.
The only solution I know is reboot.
==========>end of email>============================================
Last time I don't use esound from XMMS and I've not seen this problem
anymore.
