Here is an interesting issue that appears to be software related.
I just assembled my Franken Pre 2 yesterday, and the issue is that when I remove a 3.5 mm jack from the port, all media sound immediately stops working, and my volume rocker ceases to do anything. I have done the interactive tests and both the Volume rocker and headset jack are functioning properly. Plugging the jack back in does nothing.
Anyone have any ideas?
EDIT: Forgot to mention, rebooting does fix the problem, but not permanently. It returns immediately after I remove a headphone jack again.
