microphone or line in. On my system, I do this to adjust my playback
volume, but adjust as necessary for your sound card. Watch the case.
amixer set Master playback 100,100
In one of my keymap files (in this case, .fluxbox/keys as I use
fluxbox as my window manager) I have the following:
Shift Mod4 V :exec /usr/bin/amixer set Master 5-,5-
Control Mod4 v :exec /usr/bin/amixer set Master 3+,3+
Mod4 v :exec /usr/bin/amixer set Master toggle
which map to the soft-keys on my laptop keyboard for volume-down,
volume-up, and toggle-mute. In whatever environment you're
using, such keymaps might be configured to give you one-key
access to these three functions.
Or, they could be wrapped in a script to simplify them.
