Try to disable (not uninstall or remove) AMD audio in device manager.
And when you will update your GPU driver - choose custom install and don't select AMD audio driver.
Also check your inner monitor menu. Maybe there is an option to disable monitor speakers.
Thanks, I had not tried disabling the driver through device manager. I had uninstalled it though. I'll try this and hopefully it will work. My center monitor does have a way to disable audio and I had already done that, but my side monitors don't have that ability. Those are the ones that get turned on/off, which was the issue. I'm hoping your fix will work. Thanks.
