Knobby reboot when using external speaker on Mac Spotify App

[pnevin10]

Hi, I've noticed that Knobby will reboot when the Spotify app (Mac v1.2.21.1104.g42cf0a50) tries to use an external speaker. I can start Spotify App and Knobby can control audio. As soon as I tell the Spotify app to use an external speaker the Knobby will reboot. This problem does not occur when you use the web-based Spotify application (Chrome tested).

I can reproduce this issue on two Knobby devices with the latest firmware installed.

Working just fine with Mac Spotify App using internal laptop speaker

The Chrome Spotify app does the same thing.

What kind of external speaker are you trying to use?

Specifically, I saw this happen on my Knobby when trying to move playback onto a Sonos speaker. It looks like they are locked down behind the API:
Sonos speakers not showing in GET /player/devices

Hi @pnevin10, I've been looking into this but can't seem to reproduce the problem yet. I also suspect the issue may be related to the external speaker. Could you share the response you get from the /v1/me/player Spotify API when playing something on that speaker?

@quadule Hi there - here's the result of my API call. In my devices list within the knobby menu, I have my two Amazon Echo devices, my PC (spotify app), and 'Everywhere'. My Sonos speakers do not show up and when I use the Spotify PC app to move playback to a Sonos speaker, the Knobby sort of glitches out and seems to go into a quick boot loop. If I use the Spotify PC app to return playback to either of the Echos or my PC Spotify app, the knobby exits its boot loop.

In this case, 'Beam' is a Sonos soundbar.

As @JJSphar pointed out, it looks like Sonos speakers aren't returned in the device list. Is there a way for knobby to handle when playback is occurring on a device not in the devices list? If it's not feasible to initiate playback on a restricted device, is it perhaps possible for us to start playback on knobby, move playback to a restricted device, and then be able to control that session(skip, play/pause, etc.)?
