[Wlug] Fedora 10 and sound

I decided to install fedora 10. I understand that my laptop is old (bought in 2002). Fedora 8 had problems installing due to 256M of ram but ran fine once I got it installed. I've since upgraded the memory but fedora 10 can't play audio. Any music file I've tried lags horribly. Is there any configuration I can modify to fix the problem? Alternatively can the audio server be disabled?
