Looking in /etc/pulse I see there was a recent change to
/etc/pulse/default.pa
which may be the root of my problem.

Does anyone have a working default.pa they could post?


Am I supposed to have either /dev/dsp or /dev/snd/* on the server?
There are none of those.


I was also thinking of trying to go back to an earlier kernel
to see if that was the problem, but I cannot get grub to give
me the boot menu. What is the best way to get grub to pause
and let me choose from earlier kernels?
