I've been using this headset for almost a year now on pc and it works great and now it only works on one side of the ear. I know it's not the headset problem because I tested it on the ps3 and both were working
what's the model of the headset?
also, did you try updating the drivers?
they are the pdp afterglow universal full size one. I went to the audio manage and clicked on test from the speakers and it played the left one at regular volume then the right side was lower. I checked the levels already to see if the right side was muted. Nothing.
edit: the headset isn't set as default but when I do set it as default both would work but the sound would slowly muffle out then be muted after a while, like when I was playing League of Legends the sound would slowly start to die out when I was doing nothing
