What OS version are u running? Does sound work via the hdmi?
the latest one. And no, sound doesnt work out of anything. Was working fine, plugged into my truck, i unplugged the audio cord and now there is no sound out of anything
Is there anything lodged in the port? it sounds like something is shorting to ground making it think that there is a headphone jack connected... Maybe a piece of the chrome plating from the headphone pin.
did you try replugging and unplugging again?
On old PCs sometimes the detector inside the earplug may not trip, and so the machine still "believes" the earplugs are there, so it just cut the loudspeakers...
