Special keyboard keys stopped working

---

Hello
I use m$ 600 wired keyboard, it has some special keys (up volume, down volume, mute, calculator).
These keys stopped working without any reason. Some solution?

You can manually map the keypresses to commands.
You can use pactl or amixer for that. Just edit your keyboard shortcuts and paste the commands in there.
Alternatively you can use Xbindkeys.

Samples:

Increase Volume by 3%
amixer -q sset Master 3%+

Decrease:
amixer -q sset Master 3%-

Mute/Unmute:
amixer -q sset Master toggle

Same for pactl:
pactl set-sink-volume 0 – +3%
pactl set-sink-volume 0 – -3%
pactl set-sink-mute 0 toggle
