I'd like to see sound volume in the module pulseaudio in decibels but on the wiki page for the module pulseaudio, there is shown only that an available token for displaying volume is %percentage% and I don't know if that's all or there are others.

I can get the volume in decibels by parsing the output of pactl list sinks where is a line containing

Hlasitost: front-left: 32967 /  50% / -17,90 dB,   front-right: 32967 /  50% / -17,90 dB

among many other lines and it's quite hard to parse.

I'd like to have a token like %decibels% in the label-volume format string that makes it show the volume in decibels.
