I did get some distortion the first time I tried to play a file
yesterday but I didn't note the circumstances. Here's what I got
tonight:

Cold boot of SS20.
Play a mp3 using mpg123 with no options.
Get 'dbri0: cs4215 didn't respond to CLB (0x00)' immediately playback
starts.
Sound loud and very distorted.
Abort playback using ^C.
Play same file again, this time no error message and sound normal.
Play same file again, get error as above when playback starts but sound
still normal.
Play same file again, no error messages, sound normal.

So it looks like I get the error when playback starts but not every
time. FWIW, the box I'm testing on is running 2.0 userland and the only
other processes running are the usual daemons (syslogd, inetd, cron,
etc).

Hope that helps,
George
