TV audio problems via digital set top box

Discussion in 'Windows Media Center' started by Confused digital cable MCE User, Dec 24, 2004.

  1. I have a system-builder built MCE 2005 PC that I've got connected via DVI to
    a nice Samsung 50" DLP TV. The basic MCE functionality works and looks great
    - music, pictures, videos, etc. Sound, picture quality are fine etc.

    But I get problems as soon as I try to get my TV connection going. I've got
    Comcast digital cable via a Scientific Atlanta Explorer 3100HD digital set
    top box. Connecting the set top box via coax to my MC PC TV tuner card
    inputs (and then via my DVI connection to the DLP TV), I get a TV picture,
    but no TV sound - even if I connect the audio out connections from the set
    top box to my TV tuner card audio inputs. Rest of MCE audio works fine
    (every click of the remote comes cleanly thru the TV's speakers). Just not
    the TV audio. I can change channels fine too.

    Do I need to connect the cable box to the audio inputs of my sound card? Or
    should I keep them connected to my Hauppauge 250 MCE TV tuner card? Or do I
    need TV audio inputs at all to my PC from the set top box? Any idea why I'm
    not getting any sound? Seems very wierd.

    Thanks in advance for any insight.

    Hi,

    No, your audio in should go into your TV tuner, and the audio out from your
    PC should go to whatever speakers you use - either your PC speakers, the TV
    audio in or a surround sound system.

    Have you tried reinstalling your tuner drivers - what DVD decoder are you
    using?

    Terry

    Do you get sound when you play a DVD using MCE?

    Ignore my previous post I am not sure my removal worked correctly. Here are
    some ideas please let us know if any of them help.

    If you have speakers on your PC can you hear the TV audio using them?
    Can you hear your normal PC sounds and test them using control panel/ Sound
    devices options?
    If PC sound works properly and TV does not can you play a DVD using MCE and
    get sound?
    If sound using PC speakers is ok and can be control with the PC volume
    control can PC sounds be heard on the TV?
    You might check to be sure you connected the line out audio from your PC to
    the DVI audio in connectors and not to the audio in connectors for another
    source such as S-Video or component.

  5. Terry & JW - Thanks for your help here. A couple answers to your questions:

    - I can't hear the TV audio through my PC speakers
    - I'm using the Intervideo DVD decoder codec
    - I hear my PC audio sounds totally fine through my TV speakers, so that's
    not the issue. Music, start up sounds, etc. all sound find so the
    connections should be all fine. It's just my TV audio that isn't coming
    through at all.
    - And yes, I played a DVD and that too sounds fine through the TV speakers
    (and PC speakers)

    I'm downloading the latest drivers for the Hauppauge PVR PCI card...maybe
    that's it.

    From what I can tell, I shouldn't have to use any audio inputs into the TV
    tuner card. The coax cable should be enough.

    We'll see if the PVR card drivers help. If anything else hits you as to
    what could cause this, pls. let me know. Thanks.

    - Confused

    If you still have a problem after you reinstall the MCE drivers for your
    Hauppauge card then I suggest that you try connecting the cable direct to
    you TV tuner and seeing if you can then receive both video and audio, if you
    can then it will mean that your STB is not sending the audio as part of the
    channel 2 or 3 signal over the coax connection to our PC.
