Swap speakers

I have a pair of active speakers and I need to swap Right and Left. Simply, cabling will be much easier this way. I cannot set this in the speakers themselves, so I searched for a software solution. I googled around and found this discussion for Ubuntu. One of the posts had the solution, that works also for Slackware.

I decided to make the setup system-wide, so I opened /etc/pulse/default.pa and added the following in the bottom:

### Make some devices default
#set-default-sink output
#set-default-source input

# Reverse speakers
load-module module-remap-sink sink_name=reverse-stereo master=0 channels=2 master_channel_map=front-right,front-left channel_map=front-left,front-right
set-default-sink reverse-stereo

I rebooted and it works!

Pavucontrol even offers the option to revert to the default setting:
