We have have constant disconnect issues whenever we stream music to our soundbar via Spotify connect. At random intervals, sometimes 1 minute, sometimes 7.. our soundbar automatically changes it's own source to D-IN / TV ARC, this is with TV turned off, as a result music on Spotify pauses.
So far I have not able to track down what causes this behavior.
Reinstalled / updated firmware.
I changed HDMI cables, extra attention to proper seating of the connectors to rule out HDMI handshaking issues.
I removed the optical cable between soundbar and TV.
Did a power cycle (soundbar + tv)
Spotify reinstalled on all devices, including caches wipes.
Right now I am running dry on ideas, so it would be amazing if anyone here can shine a light, come with suggestions or if I am really lucky a solution.
My fear is that it is software related and very low on the prio list for Samsung.
