I have narrowed this problem down to the call to snd_pcm_writei that is being
called up the stack from Mono.Audio.WavData:Play(AudioDevice).

The call dev.PlaySample(buffer, read/frame_divider) confuses ALSA since it
considers one frame to be a complete sample for both channels.  So this bug is
only observable when playing stereo files.  The corrected line should read
dev.PlaySample(buffer, read/frame_divider/channels), or at least this works for
me.  If it's dependent on the AudioDevice to know this then perhaps the
division needs to be moved into the AlsaDevice class.

Either way the fix is trivial.
