Audio Problems

Hi

See Desktop 1 for specs.

Basically I have 2 HDMI ports and my graphics card and have 2 monitors connected. I can Only get Audio from one of the HDMI ports. In system properties / sound if I select monitor 1 I hear audio and if I select monitor 2 I hear no audio. If I swap the HDMI cables around I hear audio from monitor 2 and not from monitor 1.

I am dual booting with Windows 10 and everything is working fine in Windows.

Anyone have any Ideas on how to fix.

Thanks
