@Yiannis_Kouropalatis How are you getting along with this syncing problem? I’m experiencing the exact same problem: I have a BS Node2 and a Pulse Mini, Roon core running on a Mac Mini, all hard wired through ethernet.
When I group both BS devices in BluOs no syncing problems but as soon as I group the devices in Roon the problems start rather quickly.
My experience is exactly like yours. I have a Node 2 + Flex and when I control them via the BluOs app then all is great and music is in perfect sync. If I use Roon (grouping the two) then music goes out of sync within 5-10 minutes.
Indeed Bluesound claim that the issue is network related but we are ruling this out by hardwiring our devices. So far the strongest indication is that the problem will be resolved when Bluesound roll out the latest RAAT version. Other than ‘we are working on it’, there is no indication of timeline offered by Bluesound. In general, they seem to take quite a long time in resolving issues and bugs so I would not hold my breath…
As things stand, I have had to adapt and compromise. I am limiting my use of Roon for single end points only. I really do not like the BluOs app but I am having to use it exclusively for multiroom playback. My listening is 80% multiroom and 20% single end point so sadly I have to use the BluOs app most of the time.
I am definitely finding a better experience with multiroom Bluesound devices when they are controlled via the BluOs app. I still enjoy Roon but only when I use a single Bluesound endpoint.
On the other hand I also use two roon bridge endpoints (Win 10 PCs) and they sync perfectly via Roon as long as no Bluesound device is added to the group. To my mind this adds hope that if/when Bluesound rolls out the latest RAAT version then all will be fine again.
My Roon Core is installed on a MacBook pro and I carry it between two homes so two systems and two routers.
Router1 : Synology RT2600ac
Router 2 : ASUS DSL-AC68U
So there are not that many other reports but, in the last thread Mike mentions the fact that Roon is aware that syncing could be improved.
Before I’ll raise my own ticket / issue I’ll wait for BlueSound to update their RAAT implementation. According to Roon the latest update contains some improvements regarding the clocking / syncing of the slave device. So my hopes are on that update…
Just tried the workaround (many thanks @dibb) and tried grouping in BluOs first before playback via Roon. It works for a few minutes but it does not take long for music to dropout completely. Once it does I cannot restart playback via Roon at all. If I ungroup (Node 2 + Flex) via BluOs then Roon works again.
Thanks for the idea anyway
I have accepted that in my case at least, Roon & Bluesound is not working unless I stream to a single device / endpoint. No problems at all when using Roon with Roon Bridge end points but Bluesound devices need to be controlled via the BluOs app for reliable multiroom playback.
Hmm, I’m not willing to accept that because BS should be working with Roon (as it’s advertised to be Roon Ready). For me it’s also core functionality since most of the time I’m streaming to my living room and kitchen and syncing issues are very noticeable.
I want to give it a serious try to debug this issue (if possible), but I only can do that if BS has updated their RAAT SDK.
Until that time, may I ask how do you run Roon server? On what device and OS version?
Thanks for those links - some of the info was beyond my networking understanding. My ROCK install and endpoints all end up connecting via the same switch but I was wondering whether UDP for timing would still need to go via the router? Would be good to eliminate the router as potentially relevant here - for the record mine is a Bipac 7800DXL.
I have been following this topic on many threads here and on Bluesound because of the frustration of this issue. I am happy to report that with the release of BluOS 3.4 the problem appears to be solved!
FWIW… I am using a Roon Ready cocktail audio x50D connected by Ethernet cable to an eero pro and a Bluesound 2i connected by wifi and they are now playing in sync. I was very close to abandoning the Bluesound device since this functionality is imperative to its usefulness to me. (I had experimented. before the BluOS 3.4 update, with connecting the Bluesound 2i by Ethernet with no improvement in sync).
