I cannot hear anyone
Check that the headphone icon on the bottom bar is not switched on — deafened, you hear nothing.
Open the gear → Voice and video → Sound output, pick the right device and click Test sound.
Check the master volume, on the same screen, and the Windows volume.
Check that you have not muted that person: their nickname carries a muted icon. Click their name to open the volume again.
On an iPhone or an iPad, sound only starts after you touch the screen. That is a system rule.
Nobody can hear me
Check that the microphone on the bottom bar is not switched off.
Test the microphone with the Picking and testing your microphone guide: if the bar does not move, the problem is before Concordia.
If you use push to talk in a browser, the Concordia window has to be in front.
If the owner muted you on the server, a notice appears on your screen. Only he can give it back.
Echo
Use headphones. Echo is almost always your speakers coming back into your microphone.
Leave echo cancellation on in the settings.
When sharing with sound, prefer sharing a tab rather than a whole screen.
The browser says the microphone is blocked
Click the padlock (or the settings icon) next to the address, in the browser, and allow the microphone for Concordia. Then reload the page.
On Windows: Settings → Privacy and security → Microphone and leave access on for desktop apps.
Close another program that might be holding the microphone.
If you unplugged and plugged the device back in, Concordia tries again on its own within a few seconds.
It says Reconnecting…
That is your internet wobbling. Concordia tries to come back on its own and returns you to the same room. If it takes a while, reload the page; you do not lose your session. If it happens all the time, prefer a cable to Wi-Fi and avoid big downloads during the conversation.
I get no notifications
The system notice only appears when the Concordia window is not in front. When somebody calls you with
@, it always appears.Open the gear → Sounds and notices and check the mode: All, Mentions only or Nothing.
In the browser, turn the notifications switch on and accept the permission request.
On Windows, check that Concordia notifications are not switched off in the system settings or in Do not disturb.
Screenshot coming soon
