Hi,
I have a Samsung 8 Series (UN65MU8000) TV hooked up to a Sonos Beam and Sub. The Beam is connected via an HDMI Arc connection. For the past year, system has been working fine... until today. I’m no longer able to output audio via the HDMI Arc connection. The Beam shows up on my Source menu, but the TV will no longer outputs audio to it. Any thoughts? I unplugged the Beam and disconnected the HDMI cable several times and nothing. Sonos TV setup is also not working.
I submitted a diagnostic: 1231399004
Thanks
