SONOS and RadioBrowser Problems (Dropouts)

[NotCharmingAtAll]

Hi Community,
I am running MA as Add-on inside of HA, which is running inside a Proxmox VM.
I have several Sonos speakers around my house. (A Play One SL stereo pair, a Play 1 stereo pair and 2 single Play 1)
I have deleted the Sonos Add-On, and the Radio Browser Add-on from HomeAssistant and stream only to and from MusicAssistant.
Music providers are Filessystem, AppleMusic and RadioBrowser.
Everything is working perfectly well, except when I stream from RadioBrowser to the Play 1 stereo pair, then every few seconds the sound/stream drops for a fraction of a second. Very short but still annoying.
On all other speakers the stream runs flawless and other streams (Apple oder Filesystem) work also well on the Play 1 pair.
It's only the combination of these speaker pair and radio stream which is behavng like this ... very strange.
Does anyone have an idea where to start for trouble shooting?
Thanks
Matt

A lot of streaming improvements have been made in the 2.7.0 beta. You should try and test that.

Thanks! When will 2.7.0 be released?
How to install the beta?

In the beta release (2.7.0b13) the dropouts are not occurring.
Thanks a lot.
Since I will stay on the stable 2.6.x for now, I am looking forward to the release of 2.7.0.
Cheers

Did some more tests and can confirm, the behavior applies to all Sonos Play:1 models.
Btw. since 2.7.0b13 fixed the issue, I would like to understand, wether its possible to upgrade a server with a stable version (2.6.2) to the latest beta (keeping the database and all related settings) and upgrade to stable, when 2.7.0 is released?
If yes ... how? Maybe you could point me in the right direction. ;-)

Sorry that is not possible.

Sorry to hear that but thanks for the answer.
