5.1 over HMDI from PC to TV

post #1 of 12
Thread Starter 
Hey, so I was curious if that was even possible? I can get Audio to my TV with HMDi but it only gets stereo.

My set up is: PC>HMDI from 560>TV> Optical out from TV>Home theater Receiver.

My xbox is set up in a similar way and the 5.1 works: however with my PC the 5.1 isn't present. It works but it's not the Quality that I expected. I can always buy an SPDIF cable to connect it from PC to the receiver but i rather Try to get my initial set up to work (assuming it is possible)

The limitation, I think, wouldnt be with your PC or GPU, but the TV. If TV output via optical is limited to stereo then no matter how high end the rest of your components are, you will end up outputting 2.0. Whats your TV model?

HDMI is outputting PCM, your xbox is outputting dolby digital 5.1.

HDMI can output up to 8 channels via PCM, but optical can only output 2 channel PCM. Hence, you are only getting 2.0.

Your HDMi can do 5.1/7.1 without the need of a soundcard.
TV dont have the capabilities to do 5.1. Its only stereo.
You have to go direct to your receiver to get 5.1 via HDMI or Optical/Coaxial digital input.

Also in windows you need to set audio to 5.1 in sound playback properties.

yeah, I think he will be better skipping the TV and just outputting directly to the receivir via optical out. Xtreme Gamer card are really cheap in this forum and,( i had one like 5 years ago ) while I never tested optical, In that time, I don't recall having issues with it
