>Description:
Sound stops playing using totem, mplayer, or flash9 (youtube). Using system OSS. 
Tried the following without success:
* Installed audio/oss
* hint.acpi.0.disabled=1
* hint.apic.0.disabled=1

Occassionally had this issue in 6.2. Upgraded from source to 7.1-PRERELEASE. Link to tarball with output of key commands and files will be attached.
>How-To-Repeat:
Play any audio or video file.
>Fix:
Sometimes, kldload snd_via82c686.ko after login helps, but is not consistent. I have not tried compiling the driver into the kernel.
