Just as the title says.
I got my P775DM3G 120hz today.
I reinstalled windows once I got my laptop, installed all the drivers through obsidian app, but I can't seem to get my headset work properly. It seems it only detects when I plug something 2 of the ports, and sadly I can't remap them (when I plug the mic in the realtec sound configurator thingy I only get the choice between line out and side speaker out), so I can only get sound, but no mic.
I tried reinstalling the drivers, but it didn't work. It doesn't come from the headset because it works fine on my old laptop. Built-in mic appears to work fine.
