Try running this in a shell (I'm running Gentoo at the moment): $ lsmod | grep snd ... snd_intel8x0 30524 1 snd_ac97_codec 99908 2 snd_ice1712,snd_intel8x0 snd_ac97_bus 1824 1 snd_ac97_codec ... Try running this in a shell (part of the 'pciutils' package): $ /usr/sbin/lspci ... 00:1f.5 Multimedia audio controller: Intel Corporation 82801AA AC'97 Audio (rev 02) ... If you've got hardware something like this, you might consider using the "/etc/asound.conf" file from here: http://johnnypops.demon.co.uk/debian/index.html#alsa which I always end up using whatever Linux distribution I install. You'd only need the first part that starts with: # Configuration for on-board AC97 'turkey' ... down to the bit that starts: # Configuration for the Terratec EWS-88 As I understand it, the hardware only works at 48Khz and the default ASLA 'dmix' settings (which does the conversion) don't quite work with my particular hardware combination. Many other apps work ok without it, but apps using SDL often seems to have problems. (this is on old hardware: a PIII with a re-capped motherboard), cheers, John.
