For three years I have successfully used an ensemble consisting of Beam and two Play1s to play back my PC sound. This is done via an external sound card (SPDIF) and a TOSLINK cable connected to it. A few days ago the sound stopped completely! I suspect a connection with the recent SONOS controller update, the second suspect is Microsoft. I spent a total of three full days trying to find a solution - in vain. My great frustration is mixed with despair.
Here are some pieces of the puzzle from my search so far:
It is a Windows 11 PC.
A second Windows 11 PC shows the same failure.
Sound signals are displayed graphically.
Connecting an Android tablet to the TOSLINK cable: music plays!
New external sound card does not help on both PCs.
Does anyone have a brilliant idea?
Here are some screenshots for illustration.
