I have my receiver connected to HDMI4 for ARC. This suddenly stopped working for me. The TV will not see the receiver as an audio output in the sound settings.

Turn CEC off and back on TV expert settings and turn passthrough off and back on your avr
Hold power button on remote til SUHD symbol shows.
