Ubuntu 20.04 fresh installation Microphone not working

Question

I just installed Ubuntu 20.04 and the microphone is not working. It is recording only static noise.

Solution

• Install pavucontrol: sudo apt install pavucontrol
• Run it: pavucontrol
• Open Input Devices tab and check if it is not muted

• Install vokoscreen recorder: sudo apt install vokoscreen
• Go to Microphone tab, enable Audio, check your recording audio device and try to record something with it

On vokoscreen's tab you have two options: Pulse and Alsa. Try if you could use either of them for audio recording.

To check if your microphone is working, use the next commands:

to enable microphone listening

pactl load-module module-loopback latency_msec=2

to disable microphone listening

pactl unload-module module-loopback

You could also run alsamixer and check if your Mic is not muted and has at least half of its volume. Use F6 keyboard button to switch to other audio adapter if you have more than one.

Actually the answer here helped me more than the detailed question, so your decision to close this question is wrong.

Thank you man, in the vokoscreen I see that Alsa can record the audio, but Pulse can't, so this is definitely a problem with pulse audio.

I have been already testing it in skype. What do you mean by "try to enable your microphone listening " ?

@VictorVosMottor I had the same issue when microphone on my headphones had contact related issues. This way you could try to fix your microphone by moving it to change contacts position. Maybe it could help. Then just do not change its position.
