Mandriva2006 loss of sound.

I am running KDE Mandriva2006. After installing xine and gstreamer, I
have lost use of the sound card, which was functioning correctly before.
I had some error messages stating 'OSS device /dev/dsp is already in use'.
I have since uninstalled both xine and gstreamer, but the problem
remains. I have checked it on KDE and gnome, no sound on either.
I have checked using fuser /dev/dsp an lsof /dev/dep these showed there
was a process that was using this file. I killed the process, and used
mcc to reset the sound card driver, but still no sound.
I am relatively inexperienced with the detailed inner workings of Linux,
but having searched the newsgroups for a solution, but so far no luck. I
include below some of the system details.

I had a similar thing happen to me. I opened KMix went to the switches
tab and found that when I disabled the digital output jack sound
returned. I have an internal SB Audigy from a couple of years ago.
