Did you compile ALSA from source? If so, try compiling it again using the --with-debug=detect option. This is what I do: cd alsa-driver* ./configure --with-oss=yes --with-sequencer=yes --with-debug=detect You didn't give much info in your post, so people can't do much to respond to it. It helps if you tell us what you did put in your rc.modules and modules.conf. You didn't even say what chipset your sound card uses. Try doing a lspci (requires pciutils) and see if it tells you the audio chipset name and revision etc. -- Doug
