Here’s some things suggested by Apple/Sonos users to maybe try next time your Speaker(s) do not show (or play) as available in the AirPlay connection list, please try the following:
- Open the Sonos app
- Go to Settings » System » About my System
- Find the IP address of your Sonos device
- Open a browser on a device connected to your local network
- In the address bar, type http://yIP address of Sonos device]:1400/tools.htm (the whole thing should look something like “http://192.168.0.125:1400/tools.htm”, but the four numbers will/may vary). You may want to bookmark this page
- Click the “mDNS Announce” button at the bottom of the page.
- You should see a simple page with nothing but “Success”. You can now close the browser
- You should now see the Sonos device appear in the AirPlay list of devices to connect to
If the issues persist then go onto perhaps try these things…
- Restart all devices including the router and try to AirPlay again
- Remove and reinstall the App that is being used for Airplay on the sending device
- Toggle off Bluetooth, or if already off, try turning it ‘on’ on the sending device
- Turn off Cellular Data and use a WiFi only connection
- Disconnect from any other Bluetooth devices (like speakers etc.)
- Connect the sending device to the same WiFi network access point as the speaker
- Reset your network settings on your iDevice in Settings > General > Reset > Reset Network Settings
- Disable ‘Private Address’ MAC Spoofing in the iOS Network connection
- Disable WiFi calling on the mobile device
- Update iOS, and speaker firmware/software
- Move your devices away from other electronics and closer to the main router
- Renew your devices DHCP lease via the router configuration pages or better still, reboot the router as mentioned above
- Switch off any Security/VPN software installed on the sending (mobile) device
Hope the above assists to resolve your Airplay issue.
