I have been using a Beam 2 by connecting my PC and PS5 through a HDMI Switch that also had optical out. I used the optical out with the Sonos converter to HDMI and al worked well.
I have just upgraded my monitor to have HDMI 2.1 so I can run my PS5 @ 120Hz. Connecting everything up the same way I am not getting any sound. I am assuming that is because of I have introduced HDMI 2.1 or at least that is the only difference from my original set up.
I have searched high and low for a HDMI 2.1 switch with either eARC or optical out thinking that will solve the problem but i cant find anything.
Has anyone else had the same problem and if so have you managed to resolve it.
