/dev/dsp device or resource busy

Gentoo 1.4
KDE 3.1 or Gnome 2.2.2
onboard soundcard (dont know model but its pretty cheapo one)

sometimes, seemingly randomly (i konw it isnt random due to the computer being perfectly logical and incapable of illogical or random processing) when i start something that uses sound (xmms, enemy territory, etc) they return the /dev/dsp device or resource is busy

how do i free up, 'unbusy' this device
i have done a search and found the command
fuser -k /dev/dsp

however after running that, nothing changes
"/dev/dsp device or resource busy"

i have done a
# ps -A | grep arts

the arts daemon is not running

my soundcard is not supported by alsa (sdly) and so that is not an option for me until i get myself a new soundcard

any ideas or do i have to keep rebooting and hoping that what ever is using the sound device disappears as randomly as it appeared :P

thanks in advance

I've checked that lsof was installed and then tried the command. This is what I get. I'm having the same problem as the thread starter btw.

~$ lsof | grep \/dev\/dsp
lsof: WARNING: can't stat() ext3 file system /dev/.static/dev
