I could’ve sworn you used to be able to do it in Windows XP, but it’s nowhere to be found either in Win7 or my Realtek control panel.
And no, there’s no hardware way to fix this (swapping plugs, etc). I’m using Logitech X-530s which, in Logitech’s infinite wisdom, run a serial cable from the Right Front speaker to the sub. And the serial cable isn’t long enough for the Right Front speaker to reach the sub in my current configuration. It’d be a whole thing to try and move the speakers around and it’d be much simpler if I could just swap the flipping channels.
Don’t even need solder. Cut the wire, buy some lamp cord at Home Depot, strip both ends, twist them together, wrap them with electrical tape (rubber tape in between two coats of electrical if you’re one of those audiophile wankers who thinks a power cleaner does something.)
