Got a Samsung QA75QN700 and Sonos Arc. Randomally we either loose audio altogether or it keeps switching on and off. On the TV u can see that audio automatically switches between Receiver (HDMI-ARC) and Receiver (HDMI-eARC). When no audio its stuck on Receiver (HDMI-eARC). Seems to have gotten worse in the last week, setting eARC off then back to auto use to fix the problem. Been an issue right from the start.
No other devices plugged in. TV and Sonos running latest firmware. Using Sonos suplied hdmi cable. Power cycled TV and Sonos Arc.
Any ideas on how to fix this.
