I have a HW-Q700A soundbar and a 7 series TV. Everything has been working fine for well over a year, but the last few days when I'm watching TV via my Fire TV cube, the soundbar keeps switching source from eARC to D.IN for about 5 seconds, then switches back to eARC. This happens every 10 minutes or so.

Setup is as follows


TV
HDMI 1 (eARC) - Soundbar
HDMI 2 - Fire TV Cube

I also have an Xbox Series X plugged into the HDMI pass through in the soundbar. The issue doesn't happen when I'm using the xbox, only when I'm using the Fire TV cube.

I've tried resetting both the TV and the Soundbar but neither has helped.

Has anyone come across this issue before?

Hi

Came across the samen problem...

I just moved to a new house. My setup worked for 2 years without any issues, now i put up the same setting, but the issue starts tot occur...

I cannot watch my tv properly... I have to shut the soundbar down, because the sound keeps falling away when switching between the modes...

I tried everything, resetting, unplugging, different ports...

Please need help.

I cannot accept that the soundbar is broken... There has to be a solution!

Any luck on a fix?  My soundbar has been fine for 2 years. Last week had this issue of the soundbar 'searching' for input to deliver output .i.e. switches every 2 seconds DiN eArc > Blue Tooth > wifi > hdmi > TV speakers - around again in a loop.

I had a similar issue and this solved my problem. https://amzn.to/48QbEE0 It disables the CEC on whichever device is causing the interference.

I have this issue too. The CEC blocker item posted above fixes it, but it makes it impossible to control everything with 1 remote now. 

 

Anyone have another fix?
