I try many tips and do not work nothing correctly. I using Lenovo G50-45 with one microphone. I found out through the forums that the microphone track had to be split and one channel muted. Then it works, but during a call such as meet.google.com it returns to its original position and the microphone does not work again. Old Pulseaudio works well maybe new pulseaudio damage microphone settings.
When in the “meet.google.com” call, did you attempt to run pavucontrol (pulse audio volume control) and adjust the mic with that volume control ? You may need to install ‘pavucontrol’ if not yet installed.
I have NEVER used “meet.google.com” app myself, so if the issue is a problem with that app, then I can not be of assistance.
Eu tenho esse mesmo problema com meu Lenovo. Você precisa se reunir com frequência, a negócios.
No meu caso, uso um heatset e funciona para mim.
Mas há outra solução, que ainda não coloquei em prática, quem sabe você não pode fazer isso …
I tried this tutorial for the first time, but it didn’t work. Then I tried it a second time and noticed that I hadn’t set the correct channel. The second is broken and OpenSuse, Ubuntu and other OS prefer it. I rested. Good luck to you.
