Alsamixer reports "dB gain 0.00, 0.00" to -60.00, -60.00 in .5 dB steps.
Does that correspond to -120 dB somehow (both channels == 120 dB total)?

I compiled and started up jkmeter, then figured out how to output to it using qjackctl.
The alsamixer volume controls make no difference at all to jkmeter, but adjusting the
volume on mplayer does. Is this the expected behavior? I was not sure how to activate K20 or K14 given
jkmeter's interface.

You mean individual application volume controls as opposed to the sound
card mixer is preferred?

So even though turning down the apps volume control theoretically
reduces the resolution of the sound it should have no bearing on the
quality of the sound presented? Or do software controls not do that at
all?

Thanks for the help Fons. I appreciate it and your fine software as
always.
