[Bug 275998] Re: audio recording very silent

[Rocko]

I tried BIOS A12 and it hasn't made any difference - alsa still didn't
detect a digital capture volume control.

I did, however, manage to make alsa-mixer show a digital volume capture
control by copying the definition across from Hardy into the
/etc/asound.state file, doing a sudo alsactl restore, and restarting
alsa-utils.

However, the control thus created has absolutely no effect on recording
level. So it seems it is possible to fool alsa/pulseaudio into thinking
there's a control even though it doesn't write changes correctly back to
the sound card when you adjust the control.
