Try to raise the line-in mixer, it's the only setting you can change for
the internal mode.

Forget about those mixers, we don't have support for those yet.

I've never tested the MSP342* revisions, I only have the 3415 as well.

Please do:
- paste the debug-output of "boot -v" related to the bktr code.
  There will be a lot more lines in dmesg after you started a tv-app
  such as fxtv, so please include those as well.
- Try to set bktr.0.mspsimple=0 (before loading the driver, e.g. from 
  the loader or device.hints).  This forces the driver to fall
  back to the fallback-mode for MSP340* chipsets, maybe it works for
  you as well.

Could you maybe try out the card under Linux? The
BKTR_NEW_MSP34XX_DRIVER is ported from the Linux-driver, if it doesn't
work under Linux, there is little chance we get it working under

Forget about those, I don't know if they have side-effects.
If you've got a dolby-card, please set the "... .dolby" sysctl. I've
never tried it myself, but it's supposed to work.
