I have a OLED65E8PUA and Sonos Beam soundbar hooked up to HDMI Arc. It works great. I have a need to add a bluetooth transmitter via optical output. When I switch sound from HDMI Arc to Optical or any other output it jumps back to HDMI Arc.. I can make it work if I disconnect the HDMI Arc Sonos Beam soundbar. Why does my LG TV not allow sound choses with my So os Beam hooked up to HDMI Arc? I reset to factory settings and it worked for one day. Now I can not select any sound output with my Sonos Beam plugged into the HDMI Arc port. Why?

    This would be caused by the SIMPLINK CEC control. When the beam being connected via HDMI, the CEC on the TV defaults over to HDMI ARC. Try turning off the SIMPLINK CEC and this may help with getting it switched to optical.

    1) Go to Settings

    2) All Settings

    3) General

    4) SIMPLINK (HDMI - CEC)

    5) Switch off

    Hi @DGRiley570

    This sounds like it could be an HDMI-CEC issue. I recommend you try the following.
    • Go to Settings > All Settings
    • Go to the General section
    • Scroll down to where it says Simplink (HDMI-CEC) and select that.
    • Disable Simplink.
    Let me know if this helps with your issue.

    Thanks,

    -Ahmed

    I have the opposite problem, my C9 65 will not allow me to select ARC. Connected to ARC on Pioneer AVR, SImplink on.
