sonos port not working as upnp renderer from foobar2000

Hi @groove_regulator 

Thanks for your post!

Are you using the Port’s Digital Output? If so, you may be affected by an issue we’ve been investigating. Please ensure your Sonos system has the latest update which may fix the issue for you. Please be aware that we are working on this issue with a high priority and hope to have it resolved for all Port owners soon. If your system is fully up-to-date and you still get no audio via the Port’s coaxial output, you can help us by letting us know what make and model of device you have connected to your Port’s output.

In the meantime, the analogue RCE outputs on the Port should be working without issue.

If this issue does not match the issue you are experiencing, however, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.

I hope this helps.

HI @Corry P 

thanks for getting back to me, I am using both the Port’s Digital and Analogue (RCA) outs and neither currently work when I try so send a UPnP stream from foobar2000 to the Port. Foobar isn’t able to start the stream although interestingly it doesn’t throw an error it just pauses. I tried disconnecting the (ARCAM irDAC) from the Coax digtal feed from the Port but that didn’t make any difference.

The Sonos Port is running 15.2 build ..316 H/W version 1.29.1.9-2.2 Series ID A102

Looking forward to a fix, as I say the same PC can stream to the Roam and all devices that I have on my S1 system (Play 5, One SL, Connect).

Hi @groove_regulator 

Well, I am glad to hear you are not being affected by the known issue - it only affects the coaxial digital output, so if you don’t get anything from the analogue outputs either, then it must be something else. Just to be sure, I recommend testing with the analogue outputs for now.

Unfortunately, I’m not sure how much I can help you with UPnP (the implementation is largely undocumented and unsupported), but I can certainly try.

First, I want to give things the best chance of working without any reconfiguration. Please switch off the PC, the Port and your router. Once the router has been off for at least 30 seconds, turn it back on and wait for WiFi to return before turning on the Port and PC.

Next, please attempt UPnP playback to your Port from foobar2000 and if it still doesn’t work, submit a support diagnostic and reply here with the number given, and I’ll see what I can see.

If you can, please also try playing to the Port from within Windows Media Player - it’ll be good to have another source app to compare results.

Please note that, in general, we recommend setting up Music Library and allowing Sonos to index the music over the use of UPnP - in most instances Music Library will provide a better customer experience.

I look forward to hearing back from you.

Edit: I just spotted your earlier report of BubbleUPnP working - you can forget about trying WMP.

HI @Corry P  here’s the diag ref

I’ve also given a screen grab where you can see Foobar is just “stuck”

HI @Corry P restarted router/switches/wifi etc (full cold restart) - no change, issue persists.

Hi @groove_regulator 

Thanks for the diagnostics! I see no sign in them of the Port receiving any instruction to play anything, nor of a connection being made.

Combine this with the fact that you are able to play to the Port via BubbleUPnP, and I’m tempted to come to the conclusion that foobar2000 is where the problem lies, though I don’t understand why it is still able to play to the Roam. It’s certainly strange. Was there a software update for foobar2000 recently?

Just in case this is down to the network, you could try disconnecting the Port from ethernet - that way, it will be using the same network interface as the Roam, which may, for some reason, perform differently. 

I hope this helps, but please be aware it is really just a guess. Our official answer will always be to add the folder to Sonos’ Music Library and select music to play from within the Sonos app (though if you exceed the limit of ~65,000 tracks, we recommend the use of Plex instead).

HI @Corry P  with ethernet removed I get the same behaviour. I note your point on using Sonos to Index the library unfortunately (as you’re probably aware) there are some issues with Sonos and (presumably) SMB2,3 and large libraries since I regularly get errors thrown that “share has disappeared” as reported by me here 

.

One point to add, although you’re not seeing anything in the logs, there is certainly some reaction from the Port when I start the stream since as I say I can hear the DAC “click” which as I say it does when changing sample rates or inputs. To clarify, with the output in Foobar set to the Port, if I double click around a playlist, choosing tracks at random, I’ll hear the DAC “click” each time but the stream won’t start.

Hi @groove_regulator 

Looking at UPnP playback events is not something I’m used to doing. Could you please initiate playback to the Port via BubbleUPnP, then try via foobar2000, and then submit another support diagnostic for me? I’d like to compare the two. Thanks.

While you do that, I’m going to try to get some assistance (a bit tricky today because of the long weekend), as I am not entirely sure the DAC does click (though I could easily be wrong).
