oh..
i had to play a bit with alsamixer but finally i got a good result...

my setting:
- front mic boost = 50 (option: 0, 50, 100)
- Capture enabled = 65
- Capture 1 disabled (see below)
- Digital = 68
- Input Source = Front mic
- Input Source 1 = Front mic (playback - see below)


i've discovered some oddity:

- i have 2 capture device.... (capture and capure 1)
- the first one is *really* a capture device and work only if i select 
"front mic", not "mic"
- the second one is the mic playback device... and again it work only if 
i use "front mic"

should it work this way?

i don't know what "VREF80" but now capturing with mic work...

now remaining problems:
- midi hardware (my card should have it): i've loaded snd-seq-midi 
module and i've an alsa hardware device but i can't play midi files 
(they play but i hear nothing...). i've created another alsa-info log 
taken with the snd-seq-midi loaded http://pastebin.ca/909849
- no "mux","mix", or "aux" record source to directly record from desktop
- surround still doesn't work
i should have surround

but trying
speaker-test -c5 -Dplug:surround41

or any of that other devices produce this error:
Playback device is plug:surround41
Stream parameters are 48000Hz, S16_LE, 5 channels
Using 16 octaves of pink noise
Playback open error: -16,Device or resource busy

the last error repeat itself until i stop it (CTRL+C)
and i hear nothing


are some of this fixable? and can i help in some way fixing them?
thanks again... A LOT!
