Why did my desktop computer's audio stop working?
It's an HP Pavilion Core i5 running Windows 7 and "Beats" audio, whatever THAT is. Running the diagnostics software says the external speaker system is turned off, which it clearly is NOT. To test them I moved the audio plug from the rear output to the front plug in. That works but sound quality is worse and no longer adjusts the bass and treble output. Is this likely a problem with software or the sound card?
