i would recomend dumping the old sound system (OSS)
youu dont need to re-compile your whole kernel !
just go the the ALSA site, and download, configure and install the ALSA (advanced Linux Sound Architecture)
alsa tends to perform alot better than OSS.
make sure before you compile each alsa pacgake you read the output from './configure --help'
you will probably want to compile backawards compatibility with OSS since all your programs will
porbably be expecting OSS, not alsa. (yes, OSS -> AlSA emutaion works better than OSS)
anyways.... this is what i recomend.
