Question setup of PC,AVR,TV

[marcin3595p]

Hi Guys

If this is wrong place to post it please direct me to most suitable. I have a big problem with sound and my set up. I have monitor that im using for games due to its 165hz refresh rate. Its connected to pc by display port. I have also av receiver connected to pc by hdmi. AVR is connected by hdmi to TV (for movies only) by pass through output. Now, to have a sound from pc on AVR I need to have monitor and tv turn on and display needs to be duplicated. As soon as I turn off TV no sound from AVR. I have tried to connect pc with AVR by optical but no sound either. What the hell is wromg and what am I doing wrong?

thanks for all help

There may be multiple audio outputs on your Windows 10 computer. But don’t worry; you can setup them so as to play sound on different devices.

That is pretty much my setup, except that I don't have a display connected to my AVR. You need to set multiple display setup to extended instead of mirror.

If you connect the pc to avr via optical, then you are limited to stereo output, or DD/DTS which is only useful when watching movies.
