STAC9228 and Digital Microphone too low.

["Paulo Cavalcanti" <promac@xxxxxxxxx>]

Hi,

I am using the latest alsa (1.0.17) and Fedora 8
on a Dell Vostro 1400 laptop.

The only problem I still have is the digital microphone,
which sounds really too low. When I select the digital
input in alsamixer, the capture volume does not make any
difference anymore.



more /proc/asound/cards

 0 [Intel          ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xfebfc000 irq 21
 1 [VirMIDI     ]: VirMIDI - VirMIDI
                      Virtual MIDI Card 1

and I am using the following options, for loading the driver:

options snd-hda-intel position_fix=1 bdl_pos_adj=64 model=dell-3stack

The codec is Sigmatel STAC9228.

Since the mic is working, I think that it should not be difficult to raise
the gain, so that I do not need to yell.

Any suggestion will be welcome.

Thanks.
