I have a Pioneer HD Plasma TV (PDP-R04U) that is about 7 years old. I am trying to connect a computer to the TV receiver with an HDMI connection and I am not getting any sound. The connection from the display to the receiver is DVI. I have the HDMI port enabled and can get video but now sound. I currently have a TIVO box hooked up to my TV and cannot get sound out of the HDMI connection in that case either. On the TIVO box it goes through a separate fiber optic digital output. I do not have that option with a computer.


Does anyone know how to enable the sound? Or do I need to get some type of HDMI splitter to separate the audio signal out so I can input it to my amplifier? I would appreciate whatever help you might give. Thanks Ted

Assuming you are calling your Audio/Video Receiver as a "TV Receiver" then yes, your problem is that you aren't sending any audio to the AVR over DVI. Almost every computer motherboard has a digital coax/optical output for audio. If that isn't an option, a newer graphics card with an HDMI output would help.


I was corrected a while back that it is possible to send audio over DVI (it's just part of the HDMI bitstream - not a separate function), it's just that the DVI-based devices didn't support audio. HDMI devices supported audio from day one. But as soon as you convert HDMI to DVI, the DVI-based device you input-to isn't going to recognize audio part of the bitstream. And, of course, an HDMI splitter isn't going to change anything since you'll just split the same bitstream into two exact copies.

My TV has an HDMI input and my computer has an HDMI output. The computer does no have a separate audio output other than a headphones jack. My TIVO box has an HDMI output and an optical audio output. So, there is no way to get the audio out of the computer through the HDMI interface or with a splitter or without a separate audio output on the computer? Is that correct? I do not understand then the point of the HDMI output on the computer. Is that only for video without audio?


Thanks

Many video cards have a DIP switch or other method to select whether or not audio is sent over the HDMI cable. Does your computer have a selection for audio over HDMI?


I, too, am also confused about your DVI cable reference earlier.


And, no, a splitter will still not change anything. All you're doing is splitting the same signal. The video and audio are not separate lines once you are using HDMI.
