Headphone works properly but microphone is not working on my ubuntu 18.04. The input level bar doesn't change which indicates the microphone doesn't detect any sound.

Pulseeffect is installed on my laptop and i am not sure if the problem started after installing it. so uninstalled and restarted my pc but still sound input not working. Some help would be greatly appreciated, thanks.

i was having the same problem on ubuntu 18.04 LTS, running this command will get your mic working, but the volume might be a little low

pacmd load-module module-alsa-source device=hw:0,6

to increase the volumen, you may need to run alsamixer in the terminal and jack up everything with PGA in the name, but I believe the mic will work after that. Ubuntu has stumbled a bit on the support for this new audio driver

  • yeah works but decreases output volume significantly – mahfuj asif Mar 18 '21 at 04:26
  • To help others who are like me - to jack up mic volume go to Capture by clicking F4 while being inside alsamixer. Then increase the capture volume with PGA like the answer suggested. Works perfectly after this [@mahfujasif hopefully this helps you]. Also, you can add above command to 'Start Up Applications' to avoid having to run the command every time you switch on Ubuntu. Otherwise, it got reset after I shut down the computer. – Indigo1729 Jul 19 '21 at 19:30
  • I get an error : "Module load failed." Any solution to this? – OlorinIstari Jan 12 '22 at 21:29
