[pulseaudio-discuss] permanent microphone boost

I am completely ignorant about audio stacks, so I don't know if mic boost belongs in Alsa or PA. However as far as I know the only audio GUI that comes in the default installation for some distros is PulseAudio's. So from a usability point of view it would be nice to have a tick box for mic boost there. Such a tick box is for example available in Windows. 

So I am happy that I found how to solve my problem with the help of the forum, but other people are probably not so lucky!

I think I gave a detailed analysis in my last mail no?

The problem is that the option is not exposed through the PA layer to
the port selector.

Quite why that is I don't know but the solution is to get that fixed.
Hopefully, someone familiar with that bit of code can comment soon.
