ati hdmi audio problems

Hi all,

Not sure if this a hardware or general window question?!

I'm looking for help on getting audio via hdmi working 100%.

It works fine as long as my avr is on and the correct input selected on it before turning on the pc.
If I change input on the avr or turn the tv on/off, change input or turn the pj on/off (dual hdmi out on the avr) then I lose audio.

I've tried setting the monitor using the EDID trick but this didn't help..

For now I've gone back to using optical for audio.

I'm willing to purchase a cheap nvidia 210 card or such like if this will definately work..

My setup:

Windows 7
XBMC Eden
Sapphire radeon 6450
Gigabyte GA-MA785GM-US2H v1.0

Pioneer VSX-2020

Have installed latest ati and realtek drivers..


Here's hoping!

I have AMD HD6450, and it works fine with my Onkyo AVR. Have you try to update your MOBO and AVR firmware?

1. Download- VSX-2020-K
2. Download- GA-MA785GM-US2H

Thanks, I have the latest bios for my motherboard..

There haven't been any firmware releases for the amp?

I'm surprised it all works for you (turning amp on/off, changing input, turning tv on/off while keeping pc on) as it seems a well known problem with the ati cards?

Maybe, due to my Onkyo being a network AVR.......I can switches to COX, Kinect, Move, etc and switch back to HTPC without loosing sound......

I have exactly the same Problem.
HTPC A6-3500
Desktop HD 6850
Denon 1612

When I first boot my HTPC and turn the AVR on I get it works but when I switch the input or turn it off and on again the HDMI sound in Windows says no connected on both PCs.

Thebluevoice pointed me here since I made a topic about this exact problem aswell. Hope somebody points us in the right direction. :/

Anyone tried to use Linux?

Going to try everything I can tomorrow.

Well I tried a Nvidia based card (GT520) and had the same problems.

Interestingly, I bought a ssd and so did another windows 7 install, this time not installing all of the latest ati stuff, but just the driver..
This now seems to work a bit better and allows me to switch on/off change input around 60% of the time without probs..
The sound cuts out for about 6 secs when i turn the tv on/off then resumes if it works.
I've disabled the ati services though it working 60% with them enabled.
Haven't tried the EDID overide yet..

The pioneer vsx-2020 is a net enabled avr.

Think I'm going to try linux too as i'm sure its drivers deciding to halt the audio when detecting hdmi changes...

Yea I thought its something with the windows ATI driver the latest one installs so much crap.
Waiting for a download to finish and then I am going to install openelec and xbmcbuntu if that doesnt work better Win7 again but only with ATI driver and no other stuff.
