i've been trying to connect my phone headphones to the PC i hear hear the sound of the other person on the chat but my microphone doesnt work with my system. could you tell me how i could get it working
If by "phone headphones" you mean a headset with one plug, that won't work on your PC (separate jacks for audio in/out). You may be able to find some kind of adapter to split out the microphone but I don't know if that's something that exists.
Probably easiest is to go buy a cheap analog or USB microphone and use that.
