How to swap Left and Right audio channels on your PC if they are swapped with each other. My simple solution to this problem.

Just over four years ago I made a video to help you diagnose faults with your wiring, speakers or headphones.
My video "Speaker Test Video (Left and Right Audio), Ensure that your left and right speakers are connected correctly." Little did I know that it would have over 1.3 Million views by June 2016 !
Its such simple video but its very useful and used by a lot of people to find out if there earbuds are incorrectly labelled or wires are crossed over or just plain faulty

A problem that is often asked is "how can I swap the Left and Right audio channels"
Some older soundcards used to have a tick box which said "Swap LR" but not seen that for a long time.

I have the easy solution to your problem here, you need to buy the two following leads from Amazon.
These leads are adapters, The one on the left converts a 3.5mm Jack Plug into left and right audio on RCA sockets where as the lead on the right converts 3.5mm Jack Socket into left and right RCA plugs.
By connecting these two leads together you have the ability to SWAP the audio channels.

Buy these two separate items :



Once you have taken delivery of these two leads do the following :
1) Unplug your existing headphones/Speakers from your PC (thats the 3.5mm jack plug that goes into the GREEN socket on your soundcard).
2) Plug in the 3.5mm jack plug from the left lead above into that GREEN socket on your PC.
3) Now get the other lead which has the red and black RCA plugs on it and insert the RED RCA plug into the BLACK RCA socket of the other lead and insert the BLACK RCA plug into the RED RCA socket of the other lead.
4) Now plug in your headphones/Speakers plug into the 3.5mm jack socket on the adapter lead.
5) Problem solved. Left channel is now going to be routed through to the Right ear and Right channel to the left.

Hope someone finds my solution to this problem of use. if so please leave a comment or promote my solution.

My Left/Right Speaker Test video

The idea of this video is simple, it allows you to confirm that you have wired up your audio system the right way round. You may not think its important but imagine playing a fighting game and you hear the enemy to your right so you turn right to fire only to get shot because they were actually on your left side !
I discovered that my L & R cables were mixed up at the back of my computer desk and have been for months.

My speaker test video :

It may help if you play this video in Full screen mode.

When Left shows on screen there should be a voice in the LEFT speaker ONLY.
If you can hear "Left channel" in the right speaker only then this means your L & R cables are swapped over.
If you can hear "Left channel" in BOTH speakers then this means you have a short circuit OR you are using a MONO sound system.

If your system IS correct then no point in watching all 4 minutes of the video.

It will then play a voice in the left and right speakers alternating every 2 seconds from left to right, this will play for 4 minutes giving you plenty of time to fiddle around with cables etc.


The time-lapse clouds I have used as a background were filmed using my modified Canon Ixus 430 camera.

On my system the "line output" from the back of the PC soundcard was connected via a switchbox (A/B Input Source Switch Box TC-12 (Part #: 50-6220) that allows me to either send the sound to my Creative Labs speakers OR to my Hi-Fi.
The Red RCA female was connecting through to the white RCA Male that was on the end of this switch box in other words Right and Left audio were being swapped !

Hope this test video is of use to someone out there.
