Wonderful help Clemens!
For the record: This is how I now control (and mute) the volume using
XF86 keys in Fluxbox:
XF86AudioLowerVolume :ExecCommand if amixer get Master | grep "Front
Left: Playback 0 " > /dev/null; then amixer set Master mute; else amixer
set Master 3- dB; fi
XF86AudioRaiseVolume :ExecCommand if amixer get Master | grep "Front
Left: Playback 0" | grep "off" > /dev/null; then amixer set Master
unmute; else amixer set Master unmute 3+ dB; fi
any improvements are welcome, it works for me now!
thanks again!

when decreasing the master volume of my HDA-Intel
[1] card using amixer:
[1]Intel Corporation 82801G (ICH7 Family)
That is the controller, but the mixer controls are implemented in the
codec. Anyway, there is no codec that implements a combined volume/mute
control.
I can't get to minus infinity (silent).
-46.50dB is the lowest possible
value, and I can still hear sound coming from its output. I know that I
can mute the output but want to do this with one single key shortcut
(hence executing one command as the one above) to fade down the master
volume until silence.
Does anyone have an idea how to make this work? Is there a script around
that queries the actual value of the master volume and decides whether
to decrease it further or issue the 'mute' command from amixer?
You can easily write such a script. The current volume is available
with "amixer get ..."; use something like this:
if amixer get Master | grep "Front Left: Playback 0 " > /dev/null; then
amixer set Master mute
else
amixer set Master 3- dB
fi
Best regards,
Clemens
