I use a LG soundbar on my Machine when I'm not using a headset. I have 2 of these exact same sound bars and would like to use them both. Yes, I know I can already but I want to use them a little differently. I want to mount my bars vertically on both sides of my 3 monitor setup. One bar would be the left channel and one bar would be the right channel. So that leads me to my question...

Is there a way for me to customize the audio ports. We'll use the BLACK and GREEN ports. The BLACK will be the LEFT channel and the GREEN the right.

Any ideas?

It's Realtek audio device that allows port re-mapping.  Typically they will just switch the different jacks behaviour for one or other, not a custom channel mapping.

I suppose, depending on what software you were using, you could try to employ all surround channels and use software to map what you want where you want.  This would be complicated though, and would likely require using a DAW or other multi-channel aware program that allows routing.  You'd also likely need to use ASIO4ALL or WASAPI as there isn't an ASIO driver for the Realtek audio device.

Sounds like a lot of effort in my opinion, and you maybe better suited to using an external audio interface if you want to plug both in simultaneously.

Alternatively you'd probably need to make the appropriate cable splitter, which would be a 3.5mm TRS plug to a pair of 3.5mm TRS sockets, but one will have a floating left, the other a floating right, and both would share a common ground.

I was just hoping there was a driver / reg hack to do it to eliminate the extra software. If worse comes to worse I can just by an adapter that does it also..

what soundbar you have? as maybe it would be easier to go with some cables rather than with software

something like this stereo to dual mono way

I didn't think EQ APO had this kind of mapping ability.  I use it with a cheap USB headset to sort out the ridiculously bloated low end and to tidy up the mic sound, as well as boost the bejeebers out of the mic input level.  It does a pretty good job, nice bit of software.

Please do enlighten us as to how you accomplished your fix with EQ APO, I am intrigued.  All when time permits of course, no rush.
