I just noticed that sound recording is broken.  The symptoms are sound
that is full of pops and static.  I have two 10 second mp3's, one from
when recording worked, and one from after it broke (a total of 550K or
so uuencoded).

Hardware:

(from /dev/sndstat)
FreeBSD Audio Driver (newpcm) Jan  7 2000 23:42:26
Installed devices:
pcm0: <AudioPCI ES1370> at io 0xe000 irq 11 (1/1 channels duplex)
pcm1: <SB DSP 4.16> at io 0x220 irq 5 drq 1:5 (1/1 channels duplex)

It is broken for the ES1370 (and the soundblaster 16, but I'm not sure what's
at fault there -- I only tried that after there were problems with the ES1370).

This is the commit that broke it:
