Hey Niels, thanks for the attention to this mixer.
I usually talk to Takashi Iwai at ALSA when I have patches.
It's been a while, but if he's still there he's very receptive.
The last time, I helped with getting him to fix the word clock
lock indicator.

The hardware has separate gain and attenuation stages.
Several years ago someone combined the 'gain' sliders
with the 'attenuation' sliders, on the 'Analog Volume' tab,
and there was some outcry from some users because they
wanted to have independent gain and attenuation sliders
and clearly know what each slider was set at.

I argued that this combining was a good thing because
having separate gain and attenuation sliders was clumsy.
I said that as long as the combined sliders were clearly marked,
users would know that anything above the 0dB mark
would clearly signify gain.

But nothing was ever done about the slider markings.
Having them go from 0 to 164 is not really helpful.
It's not clear where the 0dB mark is.
At the very least a 0dB mark should be added.
Uh, do you feel like taking a stab at this?
IIRC it would be a bit tricky because you have to look up
the corresponding values in the IC data sheets, I think.

Thanks. Tim.
