Dropouts while listening to music.

Hi,
I'm experiencing frequent drop outs while listening to music. They are usually short (2-5 seconds). Music basically stops playing on all of the speakers in my living room at the same time, and restarts on all speakers together.

My setup is Playbar and Sub next to each other at the front of the living room, and two Sonos Ones at the back.
Playbar is wired to a Wifi router which also sits at the front of the room, around 4-5m away from Playbar and Sub.
There are also two Symfonisk lamps in the bedroom and Boost in between Living Room and Bedroom. None of the Sonos devices connect to my home Wifi, they are all on SonosNet, channel 11.

Speakers and the controllers have been updated to S2.

For this test I was playing music only in the Living Room. The "SONOS_IP_ADDRESS:1400/support/review" diagnostics page confirms that the Playbar uses channel 11 and also channel 48 to communicate with the Sub and Ones:
Mode: INFRA (sonosnet)
Operating on channel 2462
Home channel is 2462
HT Channel is 5240

I made sure to run my home Wifi network on different channels:
Channel 1 for 2.4Ghz
Channel 64 (80Mhz)
and an automatically selected channel in the upper band (currently Channel 100, also 80Mhz) for 5Ghz.

There is a few mobile phones, laptops and other devices in the room.

I've submitted Diagnostics (634910024) - does it show a direct cause of these drop outs? If there is an intereference - does it show which channel or which wifi network is interfering with Sonos?
Of course I may be wrong here, but I think we can exclude problems with the music being delivered to Playbar from a local media server - one day I've switched off router and it was still around 30-60s until the music stopped playing, so I assume Playbar is caching the songs in its memory. Also, similar dropouts occur when streaming music from an internet radio.

Thanks!

Hi @skyriver.

Welcome to the Sonos community and thanks for sharing your feedback and concern.

I would like to share with you the only details shown on the diagnostic.

Sonos Playbar is wired to the router instead of the Sonos Boost.
Playbar displayed audio dropouts based at the time diagnostic was sent.
Playbar is showing lost internet connection.

I would recommend switching the Sonos Boost with the Playbar since that is the main purpose of the Sonos Boost (to generate Sonos net). Wiring the Playbar to the router adds communication congestion with the Playbar since the Playbar is already communicating to the internet on behalf of it self, Sub, and the surrounds (idealy through Home Theater Broadcast system) however on your set up, the Playbar communicates to the internet on behalf of it self, Sub, surrounds, adding to the communication the Boost, 2 IKEA table lamp speakers.

Please let me know if this helps by switching the Playbar with the Sonos Boost. We are always here to help.

Thanks,

Hi @holsen

Thanks for your advice!

I’ve already had the points 2-4 completed but I didn’t know that switching off Beamforming is going to help in this situation too. I’ll definitely try it next time I need to troubleshoot it.

After some problems recently with high OFDM ANI levels on the Playbar and Sub (that are next to each other) I’ve decided to wire Sub to Playbar and see what happens. It turns out that it did help reduce OFDM ANI level and the whole reliability of the system.

Summarising the only two devices that I’ve got wired at the moment are Sonos Boost (wired to a secondary Wifi router) and Sonos Sub (wired to the Playbar sitting just above it).

Good luck with it. I can confirm that since posting above, 4 - 6 weeks ago, I am still drop out free. I'm really thankful for the network optimizer feature on the deco system. It automatically reassign Chanels and node…. Turning off beam forming also made a positive impact.
