I accidentaly found yet another non-working sample rate. I re-encode videos for
PDAs at 32khz, and I discovered that audio sounds jerky. After a bit of
experimenting with different sample rates I found that 31999Hz sample rate
works okay, 32001Hz work okay and only 32000Hz sounds with gaps and at a much
lower frequency than it should.

It is simple to reproduce this with a raw sound file and aplay. First, create a
raw file from a mp3 file (I use mpg123 for this), then play it with:

aplay -c -f S16_LE -r 32000 file.raw

Then try -r 32001 or 31999 and hear the difference.
