You're right, it is a codec problem. The vorbis code only configures
the mac in ov_open1(). This isn't a problem until the resampler is
used because it reconfigures the mac each time upsample() or
downsample() is called. Result: garbled output from Tremor.

I've changed the inline assembly routines in Tremor to re-init the mac
each time they're called. 48kHz Oggs sound perfect, but 24 and 32kHz
Oggs still have a fair bit of static. MP3 does too, but not quite as
much.
