That's good sign! It shows the device is configured. Do any of
the command-line tools work... mpg123 &c? Try setting the
sound device explicitly (eg mpg123 -a /dev/dsp foo.mp3). Try
it also as root.

~(0)% cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <ESS Technology Allegro-1> at io 0x3000 irq 5 (4p/1r/0v channels

There was a post yesterday explaining this. Apparently the driver
doesn't support recording (yet).

It seems to me that the driver is working, and that your problems
are somewhere higher in the stack.
