Are you using HDMI output to a surround sound reciever OC?

you try right clicking the speaker in the lower right corner of taskbar and messing with playback devices

Are you sure that your HDMI cable supports audio? Not all of them do.

IF the problem also exists on your PS3 I would blame the cable or the TV before the drivers.


No problems with HDMI output on my last 3 ATI cards.

PC to TV input via HDMI
TV to Bose Cinamate via RCA

Disable TV output to stereo. see if the TV plays any sound.

Go into Windows properties and check the audio device, you can test different configs, 44K to 192K output, Dolby, DTS etc.

I guess its possible my HDMI cable dosn't support sound. I ended up using the opticle output on the motherboard. It works fine. Awesome sound compared to the PStation. Blue ray video quality is about the same though. It still seems a little grainy. My 55" Samsung is 3yrs old. Maybe i need a new one. I'm running it in 1080. I see no difference in 1080p and 1080i.

I got an LG in June

LED with localized dimming = WIN

It simply is better than real life but srugles on non HD and standard def disc's

I was getting some sound from the tv. Although it was really faint.

Problem might be the TV then.

If you are using FFDshow codec you can override audio output settings, Such as always force AC3, and maybe that will allow your TV to pass the signal through.

I am not up on all the latest techs, I get the stuff working at my house and stop learning LOL

I know audio passthrough is pretty problematic at best with video cards, TV and Receivers though.

i been wondering about this for a little while now what's up with people building a such heavy duty setup for HTPC? i have never had a "real" HTPC before so i don't really know, my current movie computer is a Atom 330 and it really dose all i need it to do - play movies and still staid around $140 after shipping
