Speakers Detected as Digital SPDIF

Idek anymore, my speakers are being detected by windows as spdif output. Ive re-installed drivers, enabled sound in bios (i have Asus C5FZ) and even re-installed Windows 7 several times. They have worked before, but they just randomly stopped being detected. They work when i use them for my phone. Idek what else to do.


Sorry im new to the forum and didnt see a troubleshooting secion

did you plug it into the right audio jack?
