I just tried to get sound working on a LinkSys NSLU2

Debian Etch using a USB sound card.
What I discovered I find pretty strange, and would like to know some
more details. Apparently, all ALSA native clients don't
manage to play sound click-free, they actually have underruns all the
time. However, if I use OSS (via the snd-pcm-oss module) and set
libao to use the oss driver, I get perfect playback with about
20% CPU use at maxiumum by the user-space app playing/decoding files.
Does the same happen when ALSA clients play to device "hw:0" as
opposed to the default dmix device?
