I bought a new Lenovo ThinkPad-X1-Carbon-Gen-8. My mic is not working at all.
I have Multichannel sof-hda-dsp under my input tab in "Sounds". Mic is on, but seems like doesn't work.
Any idea what can be done? The few solutions in the forums did not help.
Thanks
This specific model has a multichannel input that is relatively new and although supported by Ubuntu 18.04, the device must be manually identified using PulseAudio's module-alsa-source like so:
pacmd load-module module-alsa-source device=hw:0,6
Please, note that you need to run alsamixer afterwords and unmute the newly added input device.
The above solution is discussed in detail in this post: 18.04 issues with X1 Carbon: alsamixer config + Microphone issues: What does “pacmd” do here?
It was first ( I think ) mentioned in this post: Microphone not working on ubuntu 18.04 with device Multichannel input-sof-hda-dsp
There are many possible causes of this problem.
In your System Settings or by directly clicking on the Sound icon from the bottom taskbar, go to the Input tab and check that the default microphone is set to your desired input device. Next, see that the input level is high enough to accept incoming voices. If this is clearly satisfied, then please proceed to next point.
Go to the software that is being used to input/record your voice. Configure in-software settings to fix the sound. From Software Settings > Sound > Microphone > Enabled/Disabled fix the sound issue.
If the issue is still not working out, then you have to change your software to record or input your voice.
Hope it will help you out :}
