Hi there, I've been having some real frustrating experiences trying to get my speakers to work. it all started when I replaced my hard drive after the old one died. The speakers I plugged in via audio/ headphone jack stopped working. The computer doesnt recognize any playback devices through the jack. But it will recognize my usb headphones no problem. I've tried every possible solution to this problem already listed on other sites (updating drivers, checking sound to enabled disabled audio devices,ect.) and none of them have worked. Any ideas? Also please dont post the whole "go to device manager and update drivers, or check sound to enable devices", I;ve already done that and it didnt work. Im looking for some real insight, not just a "solve all" solution.
