low sound volume with ich6

[Alexandr Krivulya]

  Hello!

I have a laptop with 82801FB/FR/FW/FRW AC '97 Audio Controller.
Sound volume on my laptop is too low, I can't hear anything through my 
laptop's speaker, but I can hear sound via external speakers, but its 
volume is very-very low.

Here is some information about my system:
