Hi,

A new version of knob.sh is available for download and testing at
http://moodeaudio.org/downloads/knob.sh.zip

This version supports mute toggle and volume stepping to better support IR remotes.

Examples:

/var/www/knob.sh 10
/var/www/knob.sh mute (this will toggle the mute state)
/var/www/knob.sh up 3
/var/www/knob.sh down 3

Regards,
Tim
