I have a new Samsung QN75Q80B TV and a Sonos Arc sound bar. The sound bar is connected via eARC. In order to get the Sonos sound bar to play, it must be the only HDMI port in use at the time the TV is turned on. I can then connect my Spectrum cable box to any of the remaining HDMI ports and Sonos will remain as my sound output. All is well with TV and/or cable functionality. However, if I turn off the TV and later turn back on with everything connected, I will not be able to select Sonos as my sound output, it keeps reverting back to TV speakers and will not allow me to select Sonos. This situation will remain constant until I disconnect the Spectrum cable box HDMI cable and re-initialize the Sonos as the selected sound output. The Sonos sound bar begins emitting sound as norm. Then, I can reconnect the Spectrum cable box HDMI and everything is back to norm. I shouldn't have to be disconnecting and reconnecting the Spectrum HDMI cable each time I turn off/turn on the TV.
