ALL HDMI Cables are brand new hdmi 2.0 wires.

Ok now the problems is, when i play any audio/movie/music whatever the case may be, the volume is extremely low. I have to really crank it up on my receiver. But if i use my xbox to watch netflix or something its extremely loud. What is going on? I am using HDMI on both the xbox to the receiver as well as the PC to the receiver and their the same HDMI cables. So why is the audio coming from my PC so much lower quality than the xbox? I have a 7.1 setup, ive read about doing the S/PDIF or optical output but that only handles 5.1 and not DTS HD MA format. So id have to remix all movies for it to play. What can i do to help the audio output from my PC to my receiver other than blasting the volume way up??

Is there an option on your devices to choose the sound output level when your output is selected as HDMI?
On win 10 if you hit the speaker icon in the bottom tray, and you get the popup, you can scroll through output devices. Each has it's own separate volume slider.

tried that, was already maxed out. I really don't understand why its so low when using the PC but extremely loud when using the xbox connected to the exact same receiver.
