I am on Windows 10 Version 10.0.18363 Build 18363.



My PC is connected to my Yamaha TSR-700 AVR via HDMI. From the AVR, I connect to the TV.

When my TV is off, and I play a CD on my PC, then I can upmix it to the surround decoder. And all my speakers are used.

When my TV is on, and I play the CD, then the AVR says PCM, and the surrounds aren't used.

HOWEVER, if I play a DVD or Blu Ray, and my TV is on, then I am getting the surround decoder I want.

For both the CD and DVD, I'm using VLC Player.

When my TV is off, then in Windows, for the output sound device, I have to select the name of my AVR. When my TV is on, then I have to select the name of my TV for the output sound device in Windows.

I had a Denon AVR for 2 weeks. It didn't make Windows change names for the sound output device, when I turned my TV on or off.

I think this is where the problem starts. How do I stop Windows from toggling between the name of my AVR, or the name of my TV, when my TV is on?
