Home Theater Rear Speakers losing sync - while playing music.
Answered
Greetings-
Just setup a home theater group using a Soundbar+ , Pulse Sub+ and 2 - Pulse Flex 2i for the rear channels.
The rear channels are on occasion getting out of sync with the soundbar, lagging behind a half to a full second.
The soundbar is using wired ethernet (cat-6), the sub is using the "bluesound" home theater group wireless, and shows a signal of -65db and is 8 feet away from the sound bar.
The 2 Flex 2I's are wireless 15 feet away from the sound bar, and show -63db for the right rear and the left rear shows -70db for wifi signal using the home theater group wifi. (far weaker signal than when the flex 2is were connected to my ASUS Wifi6 router/wireless (-49db).
Music will play in sync for a while (using both Radio Paradise MQA, and Deeper HIFI), but over time loses sync and does not recover unless the entire group is powered down and then back on again, or by switching sources (i think!).
The non theater group speakers also seem to wander off sync from time to time and can only be recovered / resynch by removing from the group and readding them.
Also look for MDNS settings in my ASUS WiFi 6 router and there is no applicable setting for MDNS (not sure that is even germain to this issue).
The wireless seems pretty reliable for most computer tasks, like web, mail and even streaming video, but the multi-speaker audio seems to have a bit of a challenge.
Also of note there is a fair amount of wifi saturation in the neighborhood, but I am often check and adjusting wifi channels on my gear to keep from getting stepped on by the neighbors wifi signals.
Wonder what are my next steps for trouble shooting...
Any help or advice is much appreciated.

Also having issues with sync and music play when adding other wireless speakers like the Pulse M's in the guest room and garage.

As always in these cases, we recommend contacting our Support Crew by selecting Settings, Send Support Request in the App so we may review log files and provide more 1:1 troubleshooting.

Some more observations:
Seems like the music plan + sync with the Home Theater Group has to do with the Virtualizer, flip the Virtualizer on while playing music, stuff gets echo-y and sounds out of sync in the Group. Flip it off, things sound better and more in sync.
Not sure the Virtualizer makes sense for music or there might be other settings that impact how it behaves (IDK).

Today I entered support request #423431.
I continued to test and diagnose the issue eliminating variables before I submitted a request with the logs.
I noticed that the home theater group was seemingly out of sync depending on what music was being played and that seemed to coincide with surround up mixer and virtualizer options. So I turned off both surround up mix and virtualizer for the "Music" preset for the group. The sync issues for the theater group went away since the rear speakers are out of the mix.
BUT...
The other players when grouped to the Home Theater Group (with surround up mix and virtualizer options set to Off) come out of sync with HTG. This for me is the larger issue.
I understand when using the surround and up mix/virtualizer will add in some delay and echo as a part of surround up mix, and this can be mitigated by turning of the UP mix and virtualizer for playing music.
But for me the other players coming out of sync with the HTG is way more annoying (especially for my wife :( ) and the area I would like assistance diagnosing.
I Look forward to hearing from you regarding the request #423431.0 -
Hey Bryon,
This issue has been going on for a LONG time

Yes it has been going on a long time.
There is a related thread here where I was able to help Support diagnose and identify the source of the sync issue. Long story short is the secondary wifi chip in the SoundBar+ appears to be the source of the lack of sync for players that are connected to the sound bar via the private SoundBar wifi.
If the players are hardwired to the soundbar via wired ethernet connections all the players stay in sync and perform as advertised.
For now I have added WiFi to Ethernet Adapters to the HTG players which make the players a part of my house wifi and not on the flakey SoundBar+ wifi. All the players play in sync. :)
At some point in the future a firmware fix will address the issue, so I can get rid of the WiFI to Ethernet Adapters.
