Hi there,

I have a Hauppauge WinTV Card (Brooktree Corporation Bt878 Video Capture) on my
Freebsd 5.2 RC box and after invoking either mplayer, fxtv, or xautv,
the video portion is rendered nicely on my desktop and I am able change the
channels however there is no sound accompanying the video.  After google'ing
it appears there are previous issues with the MSP34XX_DRIVER.  One post
suggested to add the options listed below in the kernel config file, which I did.
The problem persisted.  The /dev/mixer and /dev/dsp does function correctly
adding a timeout to the driver. 

Any patches, or suggestion would be appeciated.  
The only indication I have is that the audio portion of the ntsc stream
isn't bound to a driver-- if that's the correct term ;-)
