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

Hello,

Same issue here as well.

Appeared somewhere between Sunday March 26th and Wednesday March 29th.

Maybe linked to the launch of the Era 100 & 300 and updates with Dolby Atmos audio support.

I cannot check if analog audio works since the Port is hooked to a Bel Canto DAC 3 and it only has digital inputs.

In any case, the only use for the Port is to connect to the Bel Canto DAC in my listening room.

Sonos should know the customers that has a or some Ports.

They could send these owners an email to warn them and not start messing around with changing and testing digital coax cables like I did before finding this on the forum.

Same here! (Port with Lyngdorf)
And yes, I messed around with cables and other digital coax sources to find out 'what has been broken’. Please SONOS, warn owners and users when this is a known issue

I spent over an hour with a Sonos tech rep on this problem -- I had just purchased a new Sonos Port, and I was getting no sound on my Denon receiver -- and the tech didn’t know of the bug until he checked with his supervisor because we were getting nowhere. Total waste of my time. It is extremely frustrating to buy this new device, have it simply not work, and then have the company rep not know of the cause, then finding the cause and having no estimate of when it will be fixed. So essentially, I’ve just spent  >$400 for a useless brick. 

Having same issue. System has been working find for years, not working now. Where to look for update? Going to analog out is not an option for me, Sonance DSP amp with digital input card only.

[very, very long time Sonos user here with about a dozen devices. Also, a past beta tester that would have been happy to report this problem if I had been included in the update.]

Same here. First did all of the usual cable testing. Then I spent 2 hours driving to a buddy’s place today to try the Port with his system because I thought it was my Meridian system and I don’t have a spare system lying around that accepts digital coax inputs (because the optical output is mysteriously gone from the Port). And then a 1.5 hour chat with support - who concluded that I needed to buy a new Port. When I asked for the issue to be escalated, the tech came back and said it was a known issue… so I found this thread.

I should have looked here first… but really? Sonos broke the digital output and even the techs are not all aware of it?

Sonos - please make sure all of your tech support people are aware that if calls come in about the digital output of the Port that they save everyone hours of time and share that it is a software issue and a new device purchase is not required.

Also “No ETA” is not helpful. Is this going to take days? Weeks? How will I get updates about what is going on? Clearly I can’t use my device now… 

When I pointed out the error, it was played back as a misunderstanding. Case 04858896 if anyone wants to read the transcript.

Hi all,

Thank you for your patience. We've (literally) just deployed a software update that should resolve this issue. Please check for updates in the Sonos App, and once your Port has been updated, the issue should no longer occur (your port will have build 72.2-39316 (Port)). 
If the issue still occurs, please contact our support team, and we will of course look into it.

I can confirm the new build works. I hate to state the obvious, but consider adding a regression test.

Confirmed...fixed!!! PCM != Zero.

The update did not work for me - I just spoke to ‘support’ who suggested that the update to build 72.2-39316 only solves the problem for some Ports and that they are still investigating the issue.   The words used were

“They are still working on the fix, they noticed that for some of the Ports the update works. And for others the analog output is currently a workaround.”

So it just depends on whether you are feeling lucky…………….
