after month of problem-free playback i was stunned by a very weird playback issue that only appears on a set of stereo-paired SONOS Five.
As a senior software-engineer and network administrator i thought i have seen it all, but this leaves me buffled why this should happen. …even after checking and testing for quite a while
Maybe someone from support or from the community can give me a hint where to go next.
So here is the general situation:
ASUS X99-E WS Board in Tower
Intel Xeon E5-1630 v3 @ 3,7 Ghz
64 GB RAM
Windows 10 v21H2
Roon Remote running on a range of items like
Windows 10 (different machines including virtual machines)
Mac Big Sur (Macbook Pro Intel)
A large portfolio of iOS based Devices from iPhone 13 Pro to iPad Pro with all in between…
All Devices and PCs are up-to-date with Roon (Core and Remote) on most current release.
Sonos is running S2 on most recent software version.
Internet: 1000/1000 Mbit FTTH
Gateway AVM Fritz.Box 7590
MainSwitch TPlink managed with POE
all 1gbit Wired
WiFi by FritzBox and Mesh-Repeaters with excellent availability throuhout appartment
All Sonos use 2,4 Ghz with fixed IPv4 adresses
2x Sonos Play:1
1x Stereo-Pair of Sonos Five
1x Sonos HomeCinema (arc + sub + 2x sonos one)
When starting a stream to this specific pair playback starts but sound cuts off after ~1 second. Nevertheless playback is continuing (at least at the UI) on the remotes (aka “slider continues to move”).
This behaviour is independent from “source” and “remote”. If i use PC based-, Mac based- or iOS based Remotes… whatever sources i try to stream (different Radiostreams via internet, ‘local’ NAS based content with whatever encoding/bitness…)… it will always ends up in 1-2 sec. playback abruptly ending.
BUT: The very same combinations with the very same sources work just fine when i use other “targets” like 2 different Sonos:Play1 or a SONOS “Moviegroup” (Arc+Sub+2x One) or even using the iPhone or iPad (with the remote on it) as the target itself.
AND: The very same SONOS 5 pair that shows this behaviour is working just fine using the Sonos App for the very same sources (so it is neither a general WiFi- or connection-problem in general).
My conclusion so far… : this happened after some recent updates from roon AND sonos. So this could be a software problem.
And before anyone asks… yes, i have tried the usual and the unusual things to fix it, including restarts, new installation, manual “updates” etc. etc.
I would be very happy if someone can look into this problem and possibly show a way out of this mess.
Thanks and greetings
