Summary:                    Microphone in front bracket - very low volume
Description: 
I have mainboard MicroStar K8N Neo2 Platinum-54G - nForce3 Ultra (it's
nforce ultra chipset with integrated sound chip). This board has 7.1 audio
and audio can be recorded via "sound in" jack (stereo jack connector) or
"microphone" jack. These input jacks are placed on the back side of the
case (on the mainboard). When I connect microphone to this jack and turn
it on, it works great. But there is an option to connect some "sound
bracket" to this board. You can buy computer case which has some input
jacks on the front side and connect the cable from them to your mainboard.
So you get two more jacks. One for phones and one for microphone. If you
have headset (for internet telephony) with earphones and microphone, you
don't need to connect them to the back side of your case. You connect them
to the front side.

And this is a problem. If I connect my microphone to the front "sound
bracket", the volume is very very low. If I connect it to the back jack
(integrated on motherboard), it works normally (I can record with normal
volume). 

I think this is not a configuration problem. I tried every combination in
alsamixer and nothing helps. Always front jack has very low audio. If I
record something using it, I need set very high volume to hear something,
if I play it.

Lots of people has these computer cases with front bracket and  think it's
very confusing when it works normally in Windows and in Linux you cannot
use the front connector.
