I have a headset for my desktop computer. It's an analog device with two 3.5mm jacks, one for the headset, one for the microphone. It also has inline volume and microphone toggling.
By wire was chewed up by a cat and torn between the headphone jacks and the inline controls.
I have repaired the headset by re-soldering the wires. It works fine...sometimes.
When I plug the headset into one phone, and the microphone into another, I can play audio onto the headset and record my voice just fine on the other phone, with no crossover.
However, when I plug the cables back in to my computer, the headset works just fine, but there is nothing but what sounds like some background interference coming from the microphone when I test it. I have tried it with two sets of audio jacks on the system, both produce the same result.
Why would it work on the two phones, but not on the computer? This isn't making much sense to me and I hope it would to someone else.
