I just recently did another cvsup, and now newpcm is broken
again.  When I try to play a clip with mpg123, I hear a very
short burst of the beginning of the clip repeated indefinitely,
like so:

"ba ba ba ba ba ba ba ba ba ba ba ba ba ba".  I have the ESS
1868, of course.  Well, I (wisely) saved my old kernel as
/kernel.good and just booted into that.

Could you also say what was fixed if you get around to it?  I'd
to learn a little more about the sound driver.

Thanks for your help.
