Realtek/AMD audio conflict!

[moabak]

I'm running an:

AMD FX-6300 3.5GHz 6-Core Processor
Gigabyte GA-970A-UD3P ATX AM3+ Motherboard
XFX Radeon R7 360 2GB Core Edition Video Card

I'm having a conflict between AMD audio drivers and Realtek audio drivers. I want to just use the onboard Realtek audio. But AMD keeps overriding Realtek even when AMD is disabled in device manager. I am running three monitors. And the center is a Vizio led tv hooked up via hdmi/hdmi cable. I don't need hdmi audio to this monitor. As I am running my own speaker system from the onboard audio on the motherboard.

Realtek shows up in my computers volume control. and appears to be getting sound as the green bar moves up and down. It is marked as default too. But no audio coming out of my Logitech 5.1 speaker set.

I've been reading forum posts online all morning with no solution. Someone suggested disabling AMD sound on the motherboards bios. I will try that in a bit. But hoping for someone with a real solution that has worked.

Switch from using an HDMI cable to an HDMI to DVI cable, that will disable the audio support.

First off. Thank you for answering. VERY Very generous of you.

I'm running three monitors. Forgive me lack of proper terminology. But my wife is in the hospital. So I'm sort of running back and forth. Two lcd monitors are running off the black and white DVI outs on the video card. And my middle monitor is a led tv that is using the hdmi to hdmi cable. Is there another way to run the cabling to my monitors to accomplish what your suggesting? I do have a fourth slot out of the card that looks like an hdmi but square. I just want to make sure I get all the resolution and clearness I can out of the center tv monitor. It's the largest and newest one. Not even sure I have a DVI in on the tv.

EDIT - All I have is two hdmi inputs on the tv and a composite. And I don't think my other two lcd monitors have hdmi inputs. Just trying to figure out how to connect all three monitors and still get good video on the main tv monitor. I have lots of cabling though. Something should work.

Well, what it sounds like is that every time you turn off your TV, your computer is detecting it as removed and then every time it detects it reconnected it's switching back to using HDMI audio. HDMI and DVI are very similar electrically, HDMI is essentially a DVI signal + audio. As such you can get a cable that has an HDMI port on one end and a DVI on the other. Using one of these will not carry the audio signal and you wouldn't have the issue you're referring to.

Now, if the TV you're using doesn't have a DVI port to plug the other end into you can't just switch the cable. The reason you can't just disable the audio in the device manager is that if you reconnect then it's a new device detected. It should be remembering your default device however, not sure why it's not.

This post here claims you can disable HDMI audio entirely with a registry setting: http://forums.guru3d.com/showpost.php?p=4038262&postcount=9 Although I can't test it.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\HDAudBus\Start=4

This value disables the High Definition Audio Controller in the device manager > system devices, it needs to be disabled.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\HdAudAddService\Start=4

This value disables the High Definition Audio Device/ATI HDMI Audio Device. You don't have to uninstall the devices first and this will also free up an IRQ. After a reboot the devices will show a yellow exclamation point but you can ignore that.
