Hello there, I've been having this problem for a while now and just cant figure it out. I have the Logitech x540 5.1 surround sound system, plugged into the back of my PC. Green(front), black (rear) and orange (center) are all plugged in. Here is the playback devices window: Notice in my audio manager screenshot (below) none of the front, rear or center cables have been detected. The only way I can get audio is if I check the checkbox "Disable front panel detection", but as you can see in the screenshot below its detecting it as "front panel" and therefore I dont have surround sound as the center and rear cables still arnt detected.. Infact, only my right speaker is working with this "fix".. I just dont understand why its detecting "back panel" as "front panel" What ive tried: - Reinstalled audio drivers 100 times - Formatted my pc - Removed the front panel audio cable to my motherboard - Tried another speakers (2.1) - Flashed bios to "last good settings" This is driving me nuts, I just bought these speakers.. Could it be a hardware issue? Is it worth trying to flash the bios again to "default settings" Really appreciate any help here!
