I've been talking to my Playbar with UPnP. The GetZoneInfo command appears to be the command used by "About My Sonos System" and returns some familiar data, e.g.



code:

    <u:GetZoneInfoResponse
      xmlns:u="urn:schemas-upnp-org:service:DeviceProperties:1">
      <SerialNumber>5C-AA-FD-xx-xx-xx:F</SerialNumber>
      <SoftwareVersion>33.15-32291</SoftwareVersion>
      <DisplaySoftwareVersion>6.4</DisplaySoftwareVersion>
      <HardwareVersion>1.9.1.10-2</HardwareVersion>
      <IPAddress>10.0.x.x</IPAddress>
      <MACAddress>5C:AA:FD:xx:xx:xx</MACAddress>
      <CopyrightInfo>.. 2004-2015 Sonos, Inc. All Rights Reserved.</CopyrightInfo>
      <ExtraInfo>OTP: </ExtraInfo>
      <HTAudioIn>2</HTAudioIn>
    </u:GetZoneInfoResponse>




I'm curious about the values for HTAudioIn. It seems to represent the SPDIF port state. So far I've got:



2: Stereo

18: Dolby 5.1

21: not listening (- playing another stream?), comes up for TuneIn and Airplay via my Connect.

22: Silence



Anyone got a better reference or more data?

update, found some more:
0: no spdif input connected
2: Stereo
7: Dolby 2.0
18: Dolby 5.1
21: (not listening) playing another stream?
22: Silence

I'm sort of hoping these constants will turn out to map to some well-known digital audio standard, and aren't just arbitrary enumerations in a Sonos header file.

Also, http://<sonos_ip>:1400/status/toslink seems to decode them.

Well this paid off. I can now reverse the Playbar's automatic ungroup-on-autoplay. This PR for the 'sonos' Ruby gem makes it possible to regroup on system idle: https://github.com/gotwalt/sonos/pull/56

So I execute this in a short ruby script on my home server every minute:
code:
system.party_mode if system.groups.count > 1 && system.inactive?


As a result the "Include grouped rooms" autoplay on the CONNECT does what we want: music in every room, if the house was quiet, music everywhere but the lounge if the TV is on.

http://<sonos_ip>:1400/status/toslink seems to decode them.

Sadly some toxic, user-hostile product manager at Sonos has crippled this kind of community dev effort by removing half the useful diagnostics, including this one.

1 means "Unsupported". I have not found any mapping of this to anything else, looks like they made them up.
