ATI HDMI loss of sound on receiver input change

I've read about using older drivers to fix this issue. Personally, I just switched to a GT430 card. No issues for me anymore.

Yep. But I bet you didnt go into c:\\programs and c:\\program files and delete the AMD folders. I made the same mistake. Also, if you aren't already, run the freeware Ccleaner after removing the program and directories, scrub the registry clean. Restart the computer and then re-install 12.2.

BTW, look at the root of C and you should see the ATI-> supprt. COPY THE 12,2 or which erer PRE 12.4 to another drive before you do all this cleanup. You'll want this so you can avoid downloading all over again.

I keep a folder on one of the drives for the various Catalyst install packages just because their packages can be buggy.


It seems the critical files that AMD 12.4 screws up is the "Intel ATI HDMI support" or something similar in name.

Welcome to the world of AMD software. When it works, it works great. But they seem to have gamers in mind rather than HTPC builders.

Can you confirm your driver version? Start button, control panel, device manager, display adapter, ATI ..., right click for properties, then select the driver tab.

Strange same release number but a different date. Did it ever work correctly or did it stop working after the 12.5 release?

I can only guess it's the way you deleted the drivers. There are so many different files involved I would not be surprised that something stuck around from the 12.5 release.

I deleted the drivers from the device manager. The AMD forums recommend a program called Drive-Sweeper to completely remove their drivers.

I have the same problem with HD7970 and HD 7750 that using 12.4 driver connected to pioneer SC-LX75
I can't go back to 12.3 right?

All I know for sure is the 12.1 drivers work. I started with the 12.1 which were fine, once I upgraded the sound would stop working when I switched inputs on my Pioneer receiver.

This is indeed strange. I see Gary recommended you use Drive Sweeper And perhaps it's the only way for you to scrub your registry. But before you do that:

You used Ccleaner, right? You used the registry cleaner, and then deleted all the entries I assume. Did you RE-RUN the registry cleaner again? I've had to do that 2 or 3 times on stubborn programs before in order to completely clean a drive, and it's the only logical explanation I could come up that would explain you still having something in the registry that forced you back to 12.5

I also see you posted this was a fresh install for you. Kinda makes one lose faith in decent card when the software in this convoluted and such a pain in the backside to get working properly.

On AMDs support site there is a link to earlier drivers. I'm running 12.3 with no problems, but I've seen others who use earlier versions. Bear in mind I'm also still on the learning curve and have "AMD gum" stuck to the bottom of my shoes from stepping in it a few times. It's through these forums we all learn, and then come back to help others.

If it matters, Computers with Radeon 5670, 5770, 6450 and a 6670 all on version 12.3. Gigabyte or Asus MOBOs with Intel CPUs. AVRs are Yamahas. Windows Media Center is pretty much as per Assassin's guides.

Thank you every one, Now back to 12.3 working properly with HD 7750
Previously I thought it too old for HD 7XXX

GREAT! Glad you're up and running.

Arghhhhh, so my timing is bad to have bought a new receiver LOL

I just knew I couldn't be the only one having this source-switching problem.

Any of you experts willing to give an educated guess on whether ATI will fix this any time soon?

My current work-around is to not power off anything and not switch sources and do the plug-unplug thing when I do. I am lazy enough to live with this for a month or 2 if it's likely to get fixed with just a newer AMD Catalyst/driver package as this is pretty much just a TV room setup anyway.

Thanks

Don't hold your breath waiting for ATI to fix this issue, they only pay attention to gamers, not home theater applications. Just downgrade the drivers to 12.1 and it's going to work.

Typical with ATI drivers. I echo what an above poster said about gamers getting all the driver love from ATI.

Get the HDMI detective. Or try a different vendor.

I have a Denon and use the Intel iGPU and don't have your issues.

No one can guarantee that any specific card + receiver + HDTV + driver combination will be 100% trouble free as there are thousands of potential combinations.

I have a AMD 6670 and a Denon AVP and can sympathise with your issue having had a similar experience. Over the past month I have experimented with combinations of drivers and have attached details of what works for my system (Cat 12.3 / Audio 7706) Hopefully it will work for you too.

IMHO Changing to Nvidia may resolve your present issue but may well leave you disappointed with your perceived picture quality. For many years I only used Nvidia cards as they worked just fine. It was only when I wanted to perfect 23.976 frame rate operation I was pushed into buying an ATI card and realised the error of my ways. I can't put my finger on it but to my eyes the AMD cards always seem to give the picture more punch.

During the period of trying to resolve my sound loss issue I decided to check if Nvidia had finally improved their video quality and try to resolve my audio issue at the same time. The result was that the audio issue did not appear to be present but the video quality was just how I remembered it. That is it worked just fine but the video did not grab my attention and I was quickly re-packaging the Nvidia card to return to my supplier.

I do not wish this post to be considered an Nvidia bashing post, it is simply my personal experience and that of my close friends that have the same interest.

I do own an Intel system with inbuilt sound & graphics but have never connected to my home theatre system and cannot comment on picture quality.

I would suggest remove current AMD drivers and installing 12.6 Beta drivers.

Prior to these HDMI had problems much as you describe.

There are now 3 flavors of 12.6 beta, I have used the first or oldest but have heard the second worked as well. The third I have no info on.
