Troubleshooting

"Microphone blocked"

Browsers only expose the microphone on HTTPS pages or localhost. Serve RoomCall through a reverse proxy with a certificate your devices trust, then reload and allow the mic.

No speakers found

mDNS does not cross VLANs or subnets on its own.

  • Run RoomCall on the same network as the speakers, or
  • enable an mDNS reflector/repeater on your router (UniFi: Multicast DNS), or
  • list the speakers in speakers: in the config.

Speakers report success but stay silent

The speaker could not download the clip. Check that public_url (printed at startup) is reachable from the speaker's network — firewalls between VLANs commonly block it.

Sonos does not resume my music

RoomCall restores the previous queue and volume after the clip. Line-in, TV audio and some streaming-service sessions cannot be resumed by any third-party controller.

AirPlay is slow

AirPlay always adds about two seconds of buffering. Prefer native Sonos or Cast control for the same device when available — RoomCall does this automatically.
