Song Not Encoded Correctly

Hey there @rbrown thanks for running that test. It looks like your Cisco switch is also operating on a different Wi-Fi channel which can kinda throw a wrench in things. If possible you will want to have these operating on the same channel. each of your two speakers is now communicating directly to two different access points which may be a contributing factor in this.  Can you tell us any specs on your Cisco and Routerboard access points?

Can you also test audio playback with your Kitchen speaker wired directly to your main router? 

Is it possible to temporarily take down your switch and access points to test playback with only your router broadcasting? 

I realize that this is a lot to ask but it will help us zero in on where in your network the snag is so we can eliminate it.

Thanks for all the help and advice so far Jean.  Yes I have 3 APs and they are on channels 1,6,11 by design, so you say I should switch all to the same channel?  I can, however it not ideal as you know for wifi design/coverage/throughput.

My main router is a Mikrotik 951G-2HnD which has a wifi AP on chan 1, it is downstairs and should be what the kitchen connects to.

I have AP/switch upstairs which is a Mikrotik 941-2nD which is connected via ethernet to the router downstairs,  It is running on chan 6, and the Beam is ethernet connected to this.

I have a 3rd AP which is mostly used for outdoor devices, and it a Cisco AIR-AP1142N-E-K9 running on chan 11.

Let me know if you need any additional info on any of them.

I will try playback with kitchen directly connected and report back, and then do the same on wifi with the other APs shutdown.

No worries at all on the tests, I appreciate your assistance!

Hi @rbrown thank you for the update and the additional information. 

If you have your Sonos players on the the WiFi network then you will want to keep your access points on the same channel.

If you have a player wired to the network then you will want to keep the Wi-Fi enabled on that player so that the the two speakers can communicate through direct routing to each other.

The fewer jumps the data has to make between the router and the speaker, the cleaner the playback will be in general.

I’ll keep an eye out for an update on your playback and any additional diagnostic reports from your system.    

With a multi AP network or one with a lot of new features you give up a lot by dialing it back to be compatible with Sonos gear. I’ve been much happier with wiring at least one Sonos device to my main LAN and moving from Standard (using your WiFi) mode to Boost (using the SonosNet wireless) mode.

That lets me exploit my WiFi system’s full capabilities with no Sonos restrictions. I do only use two channels for my APs though, keeping the best quality one open for my SonosNet connectioins.

Hi Jean, I just connected the kitchen directly to the router and disabled wifi, the very first song I played skipped out with the error, diagnostic immediately after : 1254483636

Let me know if I need to test anything else.

@Stanley_4 , thank you, I agreed with your opinion to be honest regarding wifi setup, however if I have to change it I will.  I removed WIFI credentials from the app this morning, assuming that will then utilise SonosNet and therefore I would not have to mess around with my WIFI setup.  I did this but sadly it still had the same issue, many songs erroring.

@Jean C. 

I ran some extra tests to be sure;

• disabled wifi on all APs (including router)
• shutdown the ethernet port for Beam upstairs

There is one song that nearly always skips after a few seconds, this time the song made it over a minute in (but still skipped eventually).  Ive been listening for about 5 minutes since, and ….well I was just about to say it seemed better, but no, another has skipped (I am kind of glad, because in theory these addiotnal steps I took shouldn’t make any difference).

Another diagnostic in case it helps: 1184413131

Hi @rbrown, for the purposes of testing this configuration, please don’t disable the Wi-Fi interface on whichever player is wired. 

The communication directly between these two devices is a part of what I’m looking at in your system.  

Apologies, performed again with wireless enabled (but the credentials wiped), not sure if I need to readd them for this test?

Diagnostic with last song being a failure: 1972383753

Hi @rbrown thank you for that. 

I’ve been over on the other thread that you linked to regarding playback issues and this looks like an issue that we are already working to fix as we mentioned. 

Hopefully there will be an update on this soon. Keeping the Wi-Fi operational on each player will help these two devices work together better and can effect playback overall. 

This issue seems limited to one particular service and we are working to resolve it.  

Brilliant thanks Jean, I’m pleased its an issue on YT/Sonos side rather than my setup tbh!
