Precision t1700 no audio output device

I can't get any sound output from my Precision T1700 anymore. It was working via Bluetooth but stopped a few months ago and I haven't had a chance to take a look at it until last night. I tried uninstalling all the audio drivers via the device manager and installing the newest Realtek driver (6.0.1.6070 ,A00) from the dell site but that didn't work. The BIOS is already A28. 

There are no visible problems in the dev mgr but I keep getting "No output device" when I try to play anything even though wired headphones using the Aux line in on the back or front of the unit. What else can I do or check? It used to work lol
