Most problems come down to three things: the tab was shared without its audio, the browser is not Chrome or Edge, or the microphone was blocked. Below is each message Subtitled shows, what it means, and the fix.

Chrome shared the tab picture but not its sound. Press Start, pick the tab again, and switch on Also share tab audio at the bottom of the sharing dialog before pressing Share.
Firefox and Safari cannot share a tab's sound with another page. Open subtitled.live in Chrome or Edge.
The browser was told not to let Subtitled use the microphone. Click the icon to the left of the address bar, allow the microphone, and press Start again.
The sharing dialog was closed without choosing a tab. Press Start and pick the tab the conversation is in.
Chrome's Stop sharing bar ends the run on purpose. Press Start in Subtitled to share again.
Press Send a test caption. If no line appears, the browser source is missing from the live scene, hidden, or pointed at an old link; copy the source link from Subtitled again.
Your microphone is hearing your speakers. Wear headphones.
If they already speak the language the captions are in, Subtitled leaves them uncaptioned on purpose. Otherwise check that the shared tab is the one they are in.
Add them under Your words in Settings, as phrase = meaning when they need explaining.
The connection to the speech provider failed. Check your connection, or try another network if a firewall blocks it, and press Start again.
The browser cannot open that format. Export or convert it to MP4, MOV or WebM.
The file has no audio track, or nothing in it was recognised as speech. Check it plays with sound.
The sound did not reach the speech provider. Press the button again once the connection is back.
The guest page could not reach the host. The host needs Subtitled open in Podcast mode when the guest joins.
The tab was shared without its sound. Press Start, pick the tab again, and turn on Also share tab audio before pressing Share.
They cannot share a tab's audio with another page. Use Chrome or Edge.
Your microphone hears your speakers. Wear headphones.
Subtitled warns you, and auto top-up adds $10 when you drop under $2 so captions do not cut out. You can turn it off.
