BINGO!

I found this:
iface=MIXER,name='Capture Source'

When I set Mic ON through gnome-volume-control started with OSS device
value changed to 5,5


amixer -c 0 cget iface=MIXER,name='Capture Source'
-----
numid=64,iface=MIXER,name='Capture Source'
; type=ENUMERATED,access=rw------,values=2,items=8
; Item #0 'Mic'
; Item #1 'CD'
; Item #2 'Video'
; Item #3 'Aux'
; Item #4 'Line'
; Item #5 'Mix'
; Item #6 'Mix Mono'
; Item #7 'Phone'
: values=5,5
-----

I can set it this way too:

amixer -c 0 cset iface=MIXER,name='Capture Source' 0,0
-----
numid=64,iface=MIXER,name='Capture Source'
; type=ENUMERATED,access=rw------,values=2,items=8
; Item #0 'Mic'
; Item #1 'CD'
; Item #2 'Video'
; Item #3 'Aux'
; Item #4 'Line'
; Item #5 'Mix'
; Item #6 'Mix Mono'
; Item #7 'Phone'
: values=0,0

This does not have alternative Control in gnome-volume-control
started with ALSA device even in alsamixer

I think, something changed inside alsa and
gnome-volume-control/alsamixer does not know it yet.

Can I set this somewhere in alsa config files or I have to run it by
script after every reboot?


If you set it via amixer then use alsactl store that should
add it to the default. It probably also needs to be filed as
a bug somewhere (probably against Alsa) if the control
can't be made to show up in the gnome volume control
through the preferences menu (I had a similar problem
a while back with digital capture not showing up).
