Audio sync issue
I am experiencing an audio sync problem when I connect two groups of speakers. Here’s the setup and issue:
- First Speaker Group: A soundbar with a subwoofer and two rear speakers for home cinema.
- Second Speaker Group: Two small speakers.
Problem:
- Audio starts in sync but then delays occur between the two groups over time.
- This happens using Spotify and also during video playback via HDMI when adding the second group.
- I usually ungroup and group them again to reset that sync issue,
- I sometime have to kill the app and restart it (iOS) to reflect the grouping as the group is something not refresh on the app.
Thanks in advance for any advice

If you haven’t already refreshed your network, that the first thing I would try
To reset your network the following sequence is recommended:
Power off your Bluesound devices.
Power off your Router and wait five minutes (very important) before turning it on again.
Wait another five minutes for the Router to be fully up and running.
Now power on your Bluesound devices but start with the soundbar and when that’s running, the subwoofer followed by the others.
If the issue persists then in the BluOS App Please select Settings, Send Support Request so the Bluesound Support Crew can review the log file and take a closer look.

Don't forget to hardwire your speakers. Bluesound WiFi is just... not that good ;)

Yes it worked... during 1 hour and then back again.
It's becoming worse and worse to be honest, when I bought these speaker this was working as expected, and I got more because I was satisfied of these, but now, each time I want to gather my speakers I face this sync issue.
I will submit a ticket

Do also have a look to see if there is a setting on your Router called Multicast or mDNS, this needs to be turned on.

Thanks for the feebdack.
The soundbar and subwoofer are wired with Ethernet cables. The two home cinema speakers connect wirelessly to the soundbar's WiFi. The other two speakers use the router WiFi.
I have a Synology router and made a special WiFi network just for the speakers to make sure they use a faster 5GHz connection. All these speakers are in the same room as the router, and it's hard to connect them with cables.
Here is a screenshot of the router settings
I have just re-enabled the multicast option, which was not active before. Well, it was enabled on the WiFi before I set up this new dedicated network. I will try again and see...

I have a Synology Router but do flip back and forth to using the Synology wifi and another system.
Personally I would drop the VLAN and leave all Bluesound equipment together, letting devices pick 2.4 or 5.

I made a dedicated network because one speaker was using 5GHz and the other was on 2.4GHz. I wanted to see if this would help.
I just turned multicast back on for the dedicated WiFi. It's okay for a bit, but then the delay starts again and gets worse overtime.
I didn't have that in the past and my setup didn't really change since

I would however move them into your main network.

Thanks for the feedback. I've raised a ticket and I'll see the response given.
I'll bring them back into my main network too if you think that could be a better option

Did you find a solution with support?
I have the same problem with the soundbar 2i and the pulse 2 grouped. After some variable time the pulse glitches for a moment and from then is out of sync. Pausing and playing is the solution to get back in sync, but is very anoying. It seems to happen more often with hdmi playback on the soundbar than with Spotify playback. I have submitted my logs various times to support, but they keep blaming my routers arp cache. It feels very unlikely to me as I don’t have the regular consumer equipment and thus should not reach the arp cache limits in my network. Restarting the router does not affect the issue, even replaced my Ubiquity Edgerouter 12 for a Unifi Dream Machine Pro SE, wired both speakers to my LAN but did not make any difference. Multicastdns has always been enabled. It is very frustrating, so hope you found a solution and are willing to share it :).0 -
Hi Stephan
well, not yet.
I've been in contact with support, we had a session during which someone tested the speaker remotely. The issue as well as other app issues were identified and sent to their QA.
Since that, I was told that a new update was to be released but no feedback so far; my ticket is still open.
Hope this futur update could solve yours as well

Hi David, thanks for your reply. Let’s wait and hope for the best. At least positive that the ticket is still open awaiting the update release.

Hi Stephan, I'm experiencing the same issue as you. For over a year. It's funny that people are still being told that arp caches are the cause of the problems and even after you spend some $$$ to replace your Unifi equipment, use fixed IP's and hardwire everything the issue is still there. David has received the standard "we'll fix it in a future update" mail... I hope that you are patient enough, good luck.

I have the same problem. This has been going on for years. I had 1 soundbar, a sub and 2 flex speakers. I decided to just use the flex speakers in other rooms as solo speakers. The pulse bar and sub work on my TV but now I bought 2 more flex speakers and got it working for a week with the pulse bar and sub. Now I experience the out of synch as well. TV only works when I ungroup and only use pulsebar and sub. I can’t use cables so have to work with wiFi :(

Looks like I am having this issue as well. Do not seem to get anywhere with tech support. Any feedback on this would be great. It seems to me that Bluesound is selling gear with lots of issues and no fixes. The latest updated did not resolve any issues on this.
Is this related to the eArc issue? Will hooking it up over optical resolve this as the bandwidth should be more consistent? If the hardwire does not work what might be another solution.

Read the posts above and other posts about sync problems on this forum. We've been experiencing these issues for years now. This won't be fixed. They'll blame your network, router, cables and everything.
Even hardwiring doesn't fix my problem. For example, SUB+ is out of sync daily. I have to turn if off and on in the app to get it in sync again. It's ridiculous.
If they could fix this they would have done it long ago. They just don't know.

Yeah, I am thinking I have been duped as well...and I misguided my clients. Nodes are good but the rest of this line is no Bueno.

Unless it is the LG G3 TV signal for whatever reason. Only way to find out is to try it with a diff TV I guess.
