[mythtv-users] bt87x problem

hey all,

my bt878 audio capture works, but seems to capture with a sampling of
12000 instead of 32000.  myth will capture, but all audio sounds like a
record being played slow.  how do i know it's at 12000?  "aplay -r 12000
/dev/dsp1" sounds just perfect.

however myth doesn't allow 12000 for an audio capturing rate.  and the
"digital_rate" alsa option doesn't seem to have an effect.  anyone run
into this before?

info:
running the latest ubuntu, with the ubuntu myth debs.
