I'd check the following 1. mute switch on headset? 2. Disable microphone permissions in browser? Left of the URL, is there a microphone icon crossed out? 3. try recording a clip via audacity or sox utilities. 4. You can also test Firefox microphone etc with https://mozilla.github.io/webrtc-landing/gum_test.html For example, have sox record 10 sec of mono audio and store it in test.flac (ALSA's arecord is another option): $ rec -c 1 test.flac trim 0 10 Input File : 'default' (pulseaudio) Channels : 1 Sample Rate : 48000 Precision : 16-bit Sample Encoding: 16-bit Signed Integer PCM In:0.00% 00:00:02.39 [00:00:00.00] Out:106k [ ===|=== ] Clip:0 see 'man sox' to set input. -Ed
