Sound isn't playing
Browsers block sound until they're allowed to play it. Here's the fix for each kind of player.
Web browsers don't start sound by themselves unless the device allows it. If a screen is silent, first check the TV isn't muted and its volume is up, and that the screen's Sound tab isn't muted. If the Sound tab says the browser is blocking sound, use the fix for your player:
| Player | Fix |
|---|---|
| SignBlink TV app (Fire TV, Android TV) | Sound is already allowed. Check the stick's volume with its remote. |
| SignBlink app for Windows | Sound is already allowed. Click the speaker icon in the taskbar and choose the TV (HDMI) as the output. |
| Raspberry Pi (our setup) | Sound is already allowed. Right-click the speaker icon on the Pi's desktop and choose the HDMI output. |
| Fully Kiosk Browser | Settings → Web Content Settings → turn on Autoplay Videos (this covers music too). |
| Edge or Chrome kiosk shortcut | Start the browser with --autoplay-policy=no-user-gesture-required. |
| Any other browser | Click, tap or press a remote button on the player once after it starts. Sound then plays until it restarts. |
Still nothing?
- Check a music playlist is chosen on the Sound tab, that Play music covers the current time, and that you published.
- For a video's own sound, check the video has sound turned on in the playlist. Videos in playlist zones always play silently.
- On a Raspberry Pi, the sound goes to the HDMI port closest to the power socket.
