So I have my XR1 hooked up. HDMI from the TV into XR1, HMDI from PS5 into XR1, USB C from XR1 into my macbook. The right audio port going into my controller, and the left audio port is for earbuds. 
 
My issue is the audio has a buzz, I can hear that game but there's a buzz. Wondering if there's something I'm missing? 
 
Thanks for any help
