Internal Microphone issue during calls

[Viktor]

I replaced my PinePhone Pro USB C Sideboard and the mic is still very low. I looked for obstructions and there are none. My mic works fine on Postmarket OS.

Does someone know how I could increase my microphones volume past 100% on Mobian?

So the mic doesn't work properly on basically any OS, except PostmarketOS?
If so, that sounds like they have a patch that fixes things, which other OSes could benefit from.

If you want to get things fixed in Mobian, then you should bring it to the attention of the Mobian devs.
Posting this in the Manjaro sub-forums is likely not useful, but I doubt posting it in the Mobian sub-forum is going to help much (either) as I don't think the devs monitor that.

Code:

The workaround with the command below works.

sudo alsamixe
