The back panel jacks are greyed out in my realtek audio manager. I have the front panel jack detection disabled, otherwise all of the jacks are greyed out and I don't get any sound at all. I have speakers connected to the green line out of both the front and back panel, and both produce sound after a system boot up, but sometimes the back panel stops producing output, although the front panel continues to function. I didn't have this issue in xp at all, just vista. Anyone know a fix?
