Distortion

Hello all!

I am having a problem with distorted sound when using jackd. Also, I get quite
a lot af xrun-messages with unreasonable time values (e.g. 1216235685543.936
msecs).

I am hoping that someone can help me track down this problem. My operating
system is Debian Sid, i.e. jackd_0.109.2-3 and Linux 2.6.25

I get the following output on the terminal (same problem when running it with
realtime priority as root)

tmac@gotime ~$ jackd -d alsa                                              
jackd 0.109.2
