 Testing on update.1-703 on G1G1 hardware.

 Record an 8-bit WAV using GStreamer or arecord:

 {{{
  arecord -f U8 -r 16000 test.wav
 }}}

 Play it back with {{{aplay}}} and you'll hear quite a bit of noise; ditto
 if you copy the file to a non-XO and play the file there, so it doesn't
 appear to be a playback issue.

 Then record a 16-bit WAV:

 {{{
  arecord -f S16 -r 16000 test.wav
 }}}

 Play it back with {{{aplay}}} and it's clean.

 Varying the sampling frequency doesn't appear to have any affect.
 Recording with GStreamer (to both WAV and Ogg Vorbis) exhibits the same
 problem.
