Audio problem - Please help

    I installed a Hauppage Wintv card in my pc last night....the card worked fine except I had no sound....

    On further investigation I determined that the problem is not with the tv card but my motherboard....in order to get sound from the tv card you connect it's line-out to the line-in on the soundcard....

    I have an Asus K8V motherboard and I'm using the onboard sound, outputting the sound from the spdif connection to my amp which works perfectly for everything except this....the line-in connector is receiving the audio from the tv card as I can get sound if I plug in headphones to the pc and the mixer control for the line-in works but the sound coming from the line-in is not being directed out through the spdif....

    Has anyone come accross anything like this or have any ideas on a possible solution....

    Borrow a proper soundcard (pref soundblaster etc) and test with that , I'd say your onboard card is a winsc (crap) and has no internal loopback (am I making sense , the thought looks fine in my head but is harder to type)

    Asus say the following in the m/b spec about the sound: SoundMax ADI AD1980, 6-channel CODEC S/PDIF out interface

    Also I noticed that all sounds go out through the headphones, tv card and say winamp but only the winamp sounds will go through the spdif....

    A good idea....it should definitely work if both the line-in and spdif out are on the one card....one thing though is why is the audio routing ok to the headphone socket and not the spdif?

    The line in/out and headphone is analogue as is the output on the TV card. But the spdif isn't, its digital. So its doing a digital to analog conversion. Maybe the onboard sound isn't able to take a line in and play it back through the spdif at the same time. But it can with an analog signal. It could be a hardware limitation of the sound chipset.

    So basically my only option is to get a soundcard with spdif out to feed my amp?

    Don't know enough about it TBH. Ask on another forum like OcUK maybe.

    Just an update for anyone who may encounter the same problem in the future....

    I rang Asus tech-support and discovered that seeing as there's no processing done on anything coming in the line-in socket it will not be directed to the spdif digital output....

    So it looks like a new soundcard is required to do what I want to do....
