That manual is a bit outdated, but finally I found time and figured out 
how to compile and run it.

Bad news: it didn't fix the issue with mic not working right after reboot.

Good news: mentioned errors really gone.

Good news 2: today I found another issue - when non-stereo speakers mode 
is selected and I switch to Mic - laptop's built-in speakers become 
active, when I select 5.1 mode again - laptop's built-in mic become 
active, so, I was not able to use 5.1 (and any other than stereo) mode 
and mic of sound card simultaneously, this change fixed issue completely.

Good news 3: Now I know how to compile it, so I'll reply faster if there 
will be need to recompile it.
