So I got a tip from someone else, and with some experimentation, I figured out the problem (I think). The XMMS ALSA audio output plugin has some parameters for Buffer Time and Period Time. The default Period Time was 50ms. When I bumped it to 100ms, the sound is perfect. I think that's the minimum for my card, because at 80 and 90ms, the audio would repeat on a less-than-a-second portion of the somg. This seems like a wierd parameter to leave up to the user. Is there a better default than 50ms. Or better yet, is there a way to determine which Period Time is appropriate for a given sound card? I don't see anything in /proc/asound. I'd like to help the XMMS team to improve what they have, if possible.
