- Linux Mint 21.2 x86_64
- 11th Gen Framework
I updated Linux Mint Cinnamon from 21.1 to 21.2 about a month ago. The audio input issues I was having in my initial install of 21.1 came back. Previously, these issues were fixed by applying the fix mentioned at https://github.com/FrameworkComputer/linux-docs/blob/main/LinuxMint21-1-Manual-Setup-11thGen.md . However, this does not correct the issue anymore.
The issue I am having is that the input for the built-in microphone does not work. When using an external microphone (such as from a headset), input works (though requiring a little bit of fine tuning as per this thread). When I plug and unplug the external microphone, the system is clearly detecting it as I can see that it will change between “Internal Microphone Built-in Audio” and “Microphone Built-in Audio” (as appropriate) in Sound Settings. However, when working with the internal microphone nothing happens (and it is not a gain issue).
I would rule out the hardware since I have not touched it and since it seems to have been triggered by the OS version upgrade.
