TV Sound issue: Speaker output selection is showing SPDIF instead of HDMI
I have a Samsung Frame TV - QN75LS03BAFXZ (2021) and a Sonos ARC gen 2
My issue was with the TV settings, not the ARC
This is how I fixed it.
- Pulled out all cables and power supply on the backend (Sonos Connect, now Sonos Port) I did not go behind the TV to disconnect and reconnect.
- I did a factory reset on the TV.
These are the settings that worked for me. Caveat - The TV still loses the HDMI output choice that has been saved occasionally. Sometimes I must go back in and make the proper selections again.
- Go to HOME screen
- Select SETTINGS
- Set SOUND OUTPUT to Sonos Arc (HDMI-eARC)
- Go to INPUT DEVICE manager
- Go to CONNECTION
- Go to EXTERNAL DEVICE MANAGER
- Select Anynet+ (HDMI-CEC)
- Select INPUT SIGNAL PLUS and make sure that the proper HDMI selections are there. My setup has 2 HDMI inputs used: HDMI 1 & HDMI 3. Make sure that all the proper HDMI selections are selected. Mine drops one of the HDMI inputs sometimes and that’s when I have the problem.
- Go to the SOUND menu.
- In EXPERT settings make sure HDMI-eARC Mode is Auto, Digital output for audio is Pass-Through, Dolby Atmos selected & Simultaneous Optical Output selected.
It worked for me. I hope it works for you, too.
