I have a similar problem. The problem is that here is no code to
initialise the MSP340x chip, or the code isn't being run. This chip
does FM and NICAM stereo decoding and spacial sound processing and
mixing digitally (have a look at the data sheet). Because all the
audio from the tuner is routed through this chip, not having it
initialised correctly presents quite a problem if you're interested
in hearing anything.

My C and understanding of the driver is not good enough to fix the
problem, so I boot into windows and run WinTV to initialise the
MSP3401 on my card and then warm-boot into FreeBSD. This isn't such
a problem because I hardly ever turn my computer off and subsequent
reboots don't do a hardware reset.
