Can't pair new device

I have a new prototype enclosure. I followed the same set of steps I always do to build mycroft, but now the enclosure cannot pair. I see this is in audio.log:

Speak: My apologies, something unexpected has happened.
Speak: I need to restart the pairing process.
Speak: Your device is not currently registered.
Speak: An error occurred while processing a request in Pairing Skill

I dug and it turns out there were two pulseaudio processes being started - one by the user pi, which is expected, and another by the user gdm, which is new.

The solution was to add a line to both the files /usr/lib/systemd/user/pulseaudio.socket and /usr/lib/systemd/user/pulseaudio.service so that gdm can not start a second copy.


I rebooted after this change and was then able to pair the new device. Strange.

Ubuntu desktop was not starting a second pulseaudio a few months ago. Just a head’s up in case somebody else hits it.
