Have you tried playing back the audio you record in LearningBranch?
Still can't record?
Check that the volume on your speakers or headphones is up.
Check that the microphone is connected. For a Bluetooth headset, make sure it's paired correctly and that no other devices are using it. If it's a mic with a USB connector, make sure it is properly connected to the USB socket. If it's not USB, it's normally plugged into the pink socket on your computer.
Check that your microphone is not muted. Sometimes the mic has a mute button on it or on the wire that is connected to it.
Check that the volume on the microphone is up.
Check that microphone levels are up. See screenshots below.
If you still can't record, refresh the page and try again.
