[CM] snd fd error

[Bill Schottstaedt]

This is from the Jack portion of audio.c.  My guess is that after 
this error, the output ports aren't opened, so you get the other 
error, but Kjetil is the expert.

Normally, C-C will stop Snd and drop you into gdb, if you started in gdb.
C-C may be trapped in your version of Snd, so you might need (abort) or
even (exit).
