Description dashmz 2011-11-10 02:19:17 UTC 
When I'm using pactl to turn the volume up by 5% for example, it all works:

r@MacBeth:~$ /usr/bin/pactl set-sink-volume 0 +5%

but turning the volume down by 5% returns an error code:

r@MacBeth:~$ /usr/bin/pactl set-sink-volume 0 -5%
/usr/bin/pactl: invalid option -- 5

In the manpage, it is described as followed:
set-sink-volume SINK VOLUME
Set  the  volume  of the specified sink (identified by its symbolic name or numerical index). VOLUME can be specified as integer (e.g. 2000, 16384), a linear factor (e.g. 0.4, 1.100), a percentage (e.g. 10%, 100%) or a decibel value (e.g.  0dB, 20dB). If the volume specification start with a + or - the volume adjustment will be relative to the current sink volume.

So am I doing something wrong or is this a bug?

Regards

Okay, found it out now. Sorry for opening a ticket.

The correct syntax for turning down the volume 10% is:

/usr/bin/pactl -- set-sink-volume 0 -10%
