Here' the short story:
I was listening to some music, with my headset connected (through the 3.5mm jack) and working. Then I tried changing the "Default Format" to something higher. Now the audio from the output has stopped working.
I have tried restarting my PC. I have tried reinstalling the audio driver (realtek), with both the original driver (from back up) to the newest. I have tried several headsets to see if it was my headset. I have tried to set the "Default Format" back to normal (and lower values). I even tried the troubleshooting tool, but nothing works.
If I play any sound it will show up as playing, but theres no sound from any connected audio jack headsets...
My laptop is an Asus ROG G551JM, the headset I use is a QPAD QH90. The audio jack port is a combi port, both headset and mic.
