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 ;-)

You may have better luck posting to -multimedia; the bktr hackers hang out
there, if the don't pipe up here.

The fix is to get a short stereo patch cable (mini, male at both
ends) and run it from the WinTV card to line-in on your sound card,
then use mixer (or your favorite GUI front-end to mixer) to turn up
the rec level.

AFAIK, that's the only way to get sound from the WinTV card to
your sound card.

In fact, my WinTV Go! card came with the requisite cable.

I connected a cable from the line out of the Hauppauge WinTV card
to the line-in of the sound card and was unable to detect any signal.
To determine any signal from the line-out of the TV card, I connect
a head phone set to it and was unable to hear anything.

Curious if

bktr0: Detected a MSP34255?-?31 at 0x80
bktr0: STB TV/PCI, Philips FR1236 NTSC FM tuner, dbx stereo, msp3400c stereo.
pci2: <multimedia> at device 6.1 (no driver attached)

^^^^^^^^^^^^^^^^^

this is related?

Any suggestions is appreciated.
