Ok, I will have a zero gain_multiplier value in the mixer control
slider. I wish to also display in the mixer control a text
representation of the dB gain level. The problem I have is what should I
display for the 0.0 gain_multiplier setting. I.e. When it effectively
mutes the sound output at it's minimal slider setting.
a) -999.0 dB
b) Some other text entirely. Bear in mind that I only have about 4-5
chars of space to put the text in.

My question is really what should I do when the
gain_multiplier is 0.0
Do I:
a) Limit the range of the gain control to 0dB to -40 dB and have a
separate Mute control.
b) When the gain control has a gain_multiplier of 0.0, automatically
activate the Mute control.
c) Some other method.
On most pro mixing desks the fader will go down to zero gain, *and*
there will be a separate mute button. The mute may have effects beyond
just muting the signal controlled by the fader, .e.g. it could also
switch auxiliary sends or have other effects. On a real pro desk it
will be 'debounced' i.e. do a fast fade in/out.
With some exeptions, most soundcards' mixer controls are not really
meant to be used as a mixing desk, just to set gains and forget.
Many cards will have very coarse gain steps for example, and the
mute function may generate clicks (a sure killer on a pro mixer !).
