[Bug 275998] Re: internal mic capture very low volume when routed through pulseaudio

Perhaps the alsa (non-pulse) "Digital" slider controls analogue
sensitivity (pre-amp)? Marcus' hack adds software amplification - post-
amp at the very end of chain. Basically it's multiplying the samples
(both captured sound and whatever noises/distortions) by some factor.
The later the amplification is done the more distortions add up to the
sound and amplifier boosts all of them equally.

The ideal solution would be to restore the original control, still
Marcus' slider is way better than bare pulse. I'd keep his solution as a
good workaround and keep the bug open until a proper solution is in
place.

Cheers,
Tomek
