I am using an LG monitor als TV, it has only a 3.5 mm headphone audio out. My thinking was to connect the headphone out to this adapter:
and I connect to this adapter my optical adapter and HDMI cable that came with the Sonos Beam.
Sonos App lets me setup the system correct but absolutely no sound. Did I receive a faulty adapter from Amazon or will this not work at all? And no, I don’t want to use an HDMI ARC splitter because I feed the monitor with 3 sources, one of them been my Laptop with USB-C.
