Sapphire R9 270 HDMI audio issue

[dennnic]

Hello,

I need help solving the problem listed in the subject. Sometimes there is a crackling noise while playing audio on TV speakers. TV is connected via HDMI 1.4 with my R9 270. The noise is more often heard while playing PC games.
I’m using Windows 8.1 operating system, all drivers are up to date. Motherboard audio is disabled, all drivers connected to motherboard audio are removed. Speakers are just fine, tried with another TV, the same thing happened. Also, tried switching more HDMI cables, no luck there, too.
A while ago, the same setup (except for R9 270) was connected via HDMI directly to the motherboard and there were no sound issues with the on board audio.

Do you have any advice of my problem?

I've had many different audio problems in the past. One problem I remember having was distortion while browsing on the internet... scrolling or loading pages. First you should check what your CPU Usage is... if it's running extremely high... that could cause the problem.. but it sounds more like the audio driver has become corrupt. If that's the case.. just uninstall all your drivers... restart your computer... and reinstall all over again.

Here's a solution, found it by accident and it works.. Damn miracle.

Fix 2: Replacing nvlddmkm.sys in your system file – Display Driver Stopped Responding

This is a well-known fix for this issue. During the installation of most graphic drivers in Windows Vista, an old version of nvlddmkm.sys is copied into C:\Windows\System32\Drivers and not the current one in the install. As a result the new drivers are attempting to access the file dated 2006 instead of 2010. To fix this,

nvlddmkm Stopped Responding – Step 1: Download and install the latest nvidia graphic driver.

Step 2: Then go to C:\Windows\System32\Drivers and rename nvlddmkm.sys to nvlddmkm.sys.old.

Step 3: Go to nvidia directory (usually in C:\Nvidia or C:\drvvganVidia) and find the file nvlddmkm.sy_.

Step 4: Copy the file to your Desktop directory.

Step 5: Open cmd.exe by going to Start -> type cmd in the search box and hit enter.

Step 6: Change the directory to Desktop by typing chdir Desktop.

Step 7: Then, type EXPAND.EXE nvlddmkm.sy_ nvlddmkm.sys. Or,
expand -r nvlddmkm.sy_ nvlddmkm.sys

Step 8: When the expansion is complete, copy the new nvlddmkm.sys from your Desktop to C:\Windows\System32\Drivers

Step 9: Restart your computer and the problem should be resolved.

You will probably realise that any uninstallation and reinstallation of nvidia drivers will not remove the old nvlddmkm.sys file and will not overwrite it with the latest version. You have to do it manually. Nobody knows why but who cares as long it’s fixed.

Fix 3: Replacing atikmdag.sys in your system file
This is also a well-known fix for this issue if you have an ATI graphic card. During the installation of most graphic drivers in Windows Vista, an old version of atikmdag.sys is copied into C:\Windows\System32\Drivers and not the current one in the install. As a result the new drivers are attempting to access the file dated 2006 instead of 2010. To fix this,

atikmdag Stopped Responding - Step 1: Download and install the latest ati graphic driver.

Step 2: Then go to C:\Windows\System32\Drivers and rename atikmdag.sys to atikmdag.sys.old.

Step 3: Go to ati directory (usually in C:\ATI) and find the file atikmdag.sy_.

Step 4: Copy the file to your Desktop directory.

Step 5: Open cmd.exe by going to Start -> type cmd in the search box and hit enter.

Step 6: Change the directory to Desktop by typing chdir Desktop.

Step 7: Then, type EXPAND.EXE atikmdag.sy_ atikmdag.sys. Or,
expand -r atikmdag.sy_ atikmdag.sys

Step 8: When the expansion is complete, copy the new atikmdag.sys from your Desktop to C:\Windows\System32\Drivers

Step 9: Restart your computer and the problem should be resolved.
