No audio from Sonos Port digital output - "PCM Zero" signal.

Hi Ditte

I have sent a couple of diagnostics over the past few days and responded to one of your engineers via email.  It would be good to know when the issue is likely to be fixed - can you let us know please?

The volume limit workaround suggested by @ilogixaw above made no difference for me anyway  - still silence when the digital output from the Port is selected whilst the analogue output still works normally.  

Thank you.

I thought there was a problem with my system until I found this thread. 

However, this update didn’t work for me.  I still have to use the Analog output for now.

Unfortunately, that’s not the only issue I’m having.

I can’t seem to stream properly thru the Sonos app to the Port.  I can start a stream but the stream stops after about 30 seconds.  Sometimes it stops earlier if I play with the volume settings.

I can stream directly to my Move speaker which is in the same room but if I add the Port so that it outputs to my audio system, it stops.

All other functions with the Port work properly.  I can use the Line In for my CD player and turntable without any issues. 

I may have spoken too quickly.  I just tried using the digital output and it is now working.

It seems to have stabilized my streaming issue as well although it did stop on me once when I was adjusting the volume.  So it may be intermittent.  Maybe it’s a bigger issue when using Analog output. 

I’ll do some more testing when I get a chance.

I’ve been frustrated by this too, spent a good while swapping components and trying to troubleshoot before I found this thread. Hopeful this is fixed soon, analog out is not an option for me so this has me without music in one of my systems.

The update to Version: 15.3 (build 72240060) today has fixed the issue for me - digital output now working again after several weeks of not working.

Hi @only_sleeping et al

We now consider this issue fully resolved. If anyone is still experiencing problems, I recommend they get in touch with our technical support team. 

Thank you for your patience.

It only works on variable.

On fix and pass through the stream starts correctly for a few milliseconds and then turns into static noise. I tested this on two different Ports. Any fix to that?

What did the technical support team mentioned in the post previous to yours say?

I have the same issue with my KEF LS50 Wireless II setup. Bought it today. I wanted to be able to group them in the Sonos ecosystem, when I feel like it. Only option is coaxial digital, so no analog option as a fallback possible.
