Hi folks I have a short question ne ne anyone who knows the audio transfer s.pc. I bought the beam from Sonos and set up a 5.1 system on my tv. The sound signal comes from the tv on the hdmi arc port. This has worked so far who I Netflix directly on the tv I have the 5.1 sound. Now hang on the tv but synonymous still my Xbox and my pc. The Xbox I've now brought after a long room trial to send a 5.1 signal to the tv. Thank god, it works. Only my pc does not want to send 5.1 signal over hdmi to the tv. Unfortunately, he only recognizes him as a 2-channel speaker and does not want to let me change it either. Can someone tell me how I set my pc so I get from this 5.1?

Installing advanced audio drivers might work
