TV Card Surround Sound question (1 Viewer)

[Redback]

Hi all,

I'm sure there's a pretty straight forward answer to this.

I've recently been researching the Winfast DTV2000 H Plus and DTV1000S TV tuners, and am wondering how to get 5.1 audio from the movies on HD channels into the motherboards onboard sound (I'm planning to buy a Gigabyte GA-MA78GM-US2H).

My surround speakers are connected to an amp, which will then be connected to the HTPC's motherboard via optical.

I know that in the past you'd run a 3.5mm jack from the output of the tv card to the line in on the mobo, although this would only carry two channels, would it not? And connecting the TV Tuner internally to the CD or Aux-in on the mobo would also be two channel I'm guessing?

What I want to achieve is that the surround sound goes from the tuner to the mobo, and then to the amp. This way I'll be able to record HD content with the surround, and play it back.

I think there's a few of you with one of those aforementioned tuner cards.

With digital TV, an MPEG 'transport' stream is supplied by the tuner to the MediaPortal TV-server. It is then processed by TV-server to extract the video and audio data for the specific channel being viewed or recorded. In MP itself the audio is then passed to a software codec 'filter' which either decodes it (to discrete 2/3/4/5/6 channels) or passes it 'as is' to the SPDIF output - depending on the codec and audio 'renderer' settings.

So basically, you don't need an audio cable connection from tuner to motherboard - it's all done in software.

Thanks for the reply.

So basically the sound goes directly to the mobo through the PCI, just like the video? Sorry about the newb questions, btw, I'm not really up with all the latest in tuner cards. The last one I owned was an all-analog card which required the external plug into the line in.

I'm not familiar with the specific cards you mention, but yes, that's the standard situation with digital TV cards/USB sticks.
