Sound works fine for a given length of time. If you then stop listening to say, an .mp3 on xmms, the program will sometimes exit with what sounds like an audible "spike". Any attempt to access the audio immediately after this will end in failure, with the error message "could not connect to device /dev/dsp". However if you wait a while, it will work again. Sometimes. I recall this happening with an older kernel version a while back as well, except the only way to fix this problem back then was to restart the system. One of the options I chose during kernel configuration was "use persistent dma buffers". Just wondering if anyone knows what causes this. Thanks, David Shepard.
