NO audio when plugged into speakers aux on the front


Oct 22, 2016
I'm using altec lansing vs2621 2.1 audio system on windows 7 64 bit. The problem is there is an aux port on the front of my right speaker which used to work fine. I didn't use it for some time and when i plug my heasdset into it, there is no sound coming out. I checked all settings and reinstalled the audio drivers and switched the default settings and still there is no sound coming out of the aux. But my speakers are working fine.I don't see why this aux isn't working. All the connections are good and front and rear panel jacks on the cabinet are working properly. But not the aux port on the speakers. Please help me !!!!
