No need to do anything in Camilla. Its volume will be controlled by the attached USB knob.

Hi! I bougt a new volume controller and it now works! Do you know how i can increase the sensitivity of the knob? I have to turn the volume controller several turns 10-20 turns to go from 0-100.

What make/model is the knob?

The one I posted earlier takes 3 turns to go from 0 - 100. It uses a rotary encoder with detents where each detent results in +/- 1 on the moOde knob.

now I tried, it is 6 turns. I would like to increase each step to be like 5db.

Try editing the config file. The volume units are 0 - 100 not dB

Code:
pi@moode9:~ $ cat /etc/triggerhappy/triggers.d/media.conf

KEY_VOLUMEUP     1 /var/www/util/vol.sh -up 1

KEY_VOLUMEDOWN   1 /var/www/util/vol.sh -dn 1

KEY_MUTE         1 /var/www/util/vol.sh -mute
