A few months ago, I got a new desk for my computer. Before I had the desk, the living room was like this (1337 Paint skills are following): EDIT: Looks like I forgot to put the subwoofer in the images. It doesn't really matter though.



I used to sit at the armchair and the monitor and the TV were in front of me.

Now, I've put a desk (which is now where my computer is) between the R and the RR channels:



As you can see however, the audio channels are now messed up due to this change!
So, I was wondering, is there any way to make the audio channels like this?



Physically switching the cables is not an option, since there are times where I want to sit on the armchair and watch something from the computer on the TV.

I was wondering if it is possible to create a hardware-based solution that where I would be able to select which channels setting I want with a rocker switch or something similar.
The device would have 3 female 3.5mm audio ports which would be connected to the computer via 3 line in cables. The output would be another 3 female 3.5mm audio ports where the cables that are connected to the speakers would be plugged in. Depending on the state of the rocker switch, the device would either "send" the audio as it was received (which means that I'm sitting on the armchair, watching TV), or "send" it to the "correct" speakers (L->R, R->RR, RL->L, RR->RL, C->?? (possibly R and RR?)).
Is that even possible?


Thanks
