Could 'pulsed' or some other sound daemon be running in the background
preventing standard alsa/oss from accessing /dev/dsp or /dev/snd/* ?
Try running 'lsof | grep /dev/snd' and see if anything shows up.
(replace /dev/snd with any other appropriate sound/video device
files.....)
On my system that has pulseaudio running very happily:
[root@tlondon ~]# lsof | grep /dev/snd
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/tbl/.gvfs
Output information may be incomplete.
