Hi Ge,

Thanks for the response. Changing the sample rate did indeed work for me
using jack, and that's all I need. It didn't solve the problem with
alsa, however, and neither did restarting alsasound. I'm running gentoo
linux using kernel 2.6.8-r3. My system is fine now, but I'm happy to do
anything you need to help figure out the alsa problem.

| 1) try different sample rate:
|     > chuck --srate48000 -l
|     or
|     > chuck --srate44100 -l
| 2) make sure ALSA is running, the best way (I know of) is just to restart:
|     (as root)
|     > /etc/init.d/alsasound restart
|     and make sure the levels are set right
|     > alsamixer
| 3) if the above no work, there could be another incompatibility that we
| should track down.
| What linux are you running?
| Best,
| Ge!
