Bluesound Pulse Soundbar+ to Sony XR-55A90J eArc ATMOS/PCM switching deteriorates over time
An Apple TV is connected to a Sony TV via HDMI eARC and a playlist is played with mixed PCM stereo tracks and Dolby Atmos tracks. When I power the Soundbar+ up everything works well. The system switches nicely between the PCM stereo and Dolby ATMOS tracks and the BluOS app switches the display of the HDMI format based on the track being played.
However after some time (a few hours) when a PCM Stereo to ATMOS switch occurs in the playlist there is no longer sound (or sometime a "hissing" sound) and the BlueOS app continues to display the format of the previous track.
Pressing mute and unmute solves the problem.
Once the Soundbar+ is restarted (power off/on) again all is fine.
Before the Soundbar+ I used a Marantz NR1710 and had never this problem.
Anybody else experienced this behaviour?

You are totally right. I was to quick. Of course the Apple TV is connected to the HDMI 4 of the Sony XR-55A90J TV and the Bluesound Pulse Soundbar+ is connected to the HDMI eARC port (3) of the TV.

Thanks for the link. I did already review this. The cable I use is a certified HDMI cable (HDMI 2.1 certified Stouchi 8K 48 Gbps Ultra High Speed, 3 m, eARC, Dolby compatible). To be completely sure the problem is not caused by the cable I have ordered another certified cable of 2m and will try that tomorrow (Qnected® HDMI 2.1 kabel 2 meter | Gen 2 Certified | 4K 120Hz & 144Hz, 8K 60Hz Ultra HD | Ultra High Speed | 48 Gbps | eARC support). However the used cable worked perfectly well with the Marantz NR1710.

I conducted several additional tests: I replaced the HDMI cable with a certified brand new Ultra one, as recommended in the knowledge base article. I also followed the connection protocol detailed in the article, as suggested by Seppi Evans. Additionally, I reached out to the support team at my local HiFi Klubben, but unfortunately, none of these steps resolved the issue. Regrettably, I am left with no choice but to return the soundbar to Bluesound.

I did file several tickets with Bluesound support providing them with log files however I did not get any resolution from them other than the knowledge base article you also provided.

I have returned the Soundbar+ to Bluesound and bought a similar one via Hifi Klubben. This Bluesound Pulse Soundbar+ works perfectly well. No issues at all since 2 days while with the previous bar it was max 2 hours. So in the end it was broken hardware creating intermittent problems.
