I recently purchased an HDMI Switch with audio extraction to try to fix the audio delay issue between the Sonos Beam and the LG OLED C7 TV. The switch I purchased was the JTECH-SWE31 which supports ARC.
When I hooked everything up today, the audio and visual worked fine. However, I can’t control the Sonos Beam’s volume with the LG remote anymore. I have ARC enabled on the switch and the TV (LG Simplink) as well. The new HDMI cable I purchased supports up to 18 Gbps.
My setup currently looks like this:
Switch HDMI In 1: Xbox One X
Switch output: TV HDMI In 2 (ARC)
Switch optical out: Sonos Beam via optical to HDMI adapter
Two things I noticed:
- In the Sonos app when I click “TV Setup”, it says “HDMI ARC not detected. Make sure the HDMI cable is connected to the ARC port and your TV is on”.
- if I turn ARC off on the HDMI Switch, the TV output switches back to the TV speakers.
Does anyone know how to troubleshoot this issue? Really appreciate any responses here.
