Hi,
I have a beam with 2 Sonos One as surround speaker connected to my tv ( Beam to ARC). I also have a Windows 10 PC connected to the TV with and hdmi cable that I use for gaming and listening Youtube. I play game on the PC using the TV as monitor. In the pc audio setting, I select the TV as the audio outpout. Normally, the game or Youtube sound is surround 5.1. I use this setup for a while now and all was working fine till today. Now, the sound only come out of the Beam (no surround).
I guess the issues come from my pc because if I listen TV or Netflix, the surround sound work well. I also know that the speaker are well configured because if I use the 3 piece separatly, they all play the PC sound (at the same time if I use party mode).
I made a few search and see that in the PC’s sound setting, in the TV speaker property, I only have the stereo option, no 5.1 sound option, like if the PC was not recognizing the home theater connected to the TV. The device cannot get more than 2 channel.
Do somebody has an idea of what the solution could be? Thank
