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

Hi Folks, my Sonos Port is plugged in to a Lyngdorf amplifier via digital coax and has worked fine since I set it up initially. However, I’m not hearing any sound from the Port now, and the amp says it’s receiving a “PCM Zero” signal - it was fine on Sunday but no sound from any source on via the Port now. Has an update changed something? Any help would be hugely appreciated, thanks!

    Same here. Port connected to a Cambridge DAC Magic100. Tested both S/P DIF input ports available on the DAC. Both signal 44.1 input but stay silent.

    I work for an audio store and we are Sonos dealers experiencing the same problems with out demo ports. It’s unreal to me that they would release an update that cooked the Digital out. I’ve tried our Port on the Parasound Hint 6, Arcam DACir-II, and the Rega Saturn CD Player DAC, and none of them work. It is completely unreal!

    Have you provided any data to Sonos about it? While it’s mildly helpful to share your shock with this community, it might go a lot further if you were to share hard data with Sonos, so the engineers might address this issue more speedily.

    Same problem here, since last update the digital output isn’t working… how long doesn’t it take to release a rollback? 
    we have clients asking to get rid of Sonos already… this is unacceptable.

    We have a bunch of clients with Port’s that have broken DIGITAL OUT since the last update… Thanks sonos!

    Hi @only_sleeping and all,

    Our engineers are aware of this issue and are currently investigating as a priority while working towards a fix, however we do not have an estimate on when this will be resolved to share at this time.

    In this case, the analog output will still work and we would recommend using this if possible.

    If the analog output isn’t working, then you may be experiencing a different issue and I would recommend reaching out to our support team.

    I hope this information helps!

      Whilst I appreciate Sonos acknowledging the issue on the forum, it’s worth noting a lack of an apology or admission that the update has caused the issue. 

      How does a mistake like this happen?

      Why haven’t they rolled back the update?

      What compensation are they willing to offer customers whose devices they have (hopefully temporarily) crippled?

      It can also be added, when you use the analogue output and quickly operate the balance control, the bass and treble sliders changes randomly.

      Same issue. Just installed a new Port yesterday.  RCA analog works but zero sound via the digital coax connection. Note the port completed an update yesterday as well.
