[pulseaudio] volume control with multimedia keys ?

[cynyr]

#!/bin/bash
[[ $0 == pa_vol_down ]] && _down=true 
[[ $1 ]] && let _vol_increment=$1*655 || _vol_increment=655
_full_line=`pacmd dump|grep "set-sink-volume"`
_sink_cmd=`echo $_full_line|cut -d" " -f1`
_sink_id=`echo $_full_line|cut -d" " -f2`
_sink_vol=`echo $_full_line|cut -d" " -f3`
[[ $_down ]] && let _vol=$_sink_vol-$_vol_increment || let _vol=$_sink_vol+$_vol_increment
[[ $_vol -lt 0 ]] && _vol=0
[[ $_vol -gt 65536 ]] && _vol=65536
pacmd $_sink_cmd $_sink_id $_vol > /dev/null

 [[ $0 == pa_vol_down ]] && _down=true

should be

 [[ ${0##*/} == pa_vol_down ]] && _down=true

to avoid problems where the full path is used.

Other than that great script. I like how bash handles the conversion from hex to decimal on its own.

I'm using a ruby script that actually changes all sinks at the same time - which comes in handy when you've suddenly started using an external USB speaker and all your keybound scripts work with only one sink.

I can't take credit for most of it - I forked and tweaked it a tiny bit. The original script is here: https://gist.github.com/814634; I couldn't get it to run because of something in the muting code, so I fixed that and added in some output in case someone wants to send it to notify-osd or somesuch. Mine's at: https://gist.github.com/1791270.
