I purchased and installed a home theater system with a Beam Gen 2, Sub Mini, and (2) ERA300 surrounds. After installation I encountered persistent issues with streaming music from within the Sonos app using Apple Music and Amazon Music. I made several calls to Sonos support and allowed a support person to connect into my network and run tests on the Beam Gen 2. No matter what we tried the issue persisted. I've put this together so that if others are having this issue they may benefit from my endeavors and perhaps offer some help !
Here is what I experienced within the Sonos app, so much so that it is unable for streaming music.
- Message: Couldn't play AAA. The connection to Apple Music was lost.
- Message: Couldn't play AAA. It's not encoded correctly.
- Pauses, and skips while playing music.
So, after hours for frustration here is what I did ----->
The Sonos app:
- Remove ALL speakers from my system.
- Settings -> General Settings -> Forget Current System.
- Account -> App Preferences -> Reset App.
- Close app.
- Re-open app.
- Remove app.
Apple Music app: Remove.
iPhone: Power off. Wait 15 minutes. Power on.
Reset Beam Gen 2 and ALL speakers to factory settings.
Power off ALL speakers, but leave the Beam Gen 2 powered on. Why? I want to configure my system with just the Beam and then try Apple Music within the Sonos app before adding any more components.
Install Apple Music app.
Install Sonos app.
Speaker or Component. (login into Sonos account), says yes to everything, find the Beam. Proceed through setup. Beam applies a firmware update. Do not add a TV.
Your Services -> Click on + button -> Content Services -> Click on Apple Music circle -> Add to Sonos -> Authorize -> (input Apple ID password) -> (complete setup).
I DID NOT ALTER ANY OTHER SETTINGS, BUT YET THE ISSUES PERSIST !
My Observations:
- There could be an issue with my network however Sonos support connect to my computer and verified that my network was good. I have Fios 300Mbps service, CR1000A, no extenders, no repeaters. The router and Beam are in the same room, about 15' apart.
- There could be an issue with the Sonos app, but I don't think so.
My Conclusion: There is a hardware/firmware issue with the Beam Gen 2. And, with the minimal setup as described above, the issue is not caused by adding other components and/or by altering any of the out-of-the-box settings.
