Dell Precision 5510 Ubuntu issues (sound, touchpad, external projector)

I recently bought a Dell Precision 5510 with Ubuntu 14.04 factory installed.   When adding common packages to get the machine up and running for work the display eventually disappeared and the machine just booted to a black screen.  I then installed 16.04 but have issues with the sound, touchpad and external monitor. 

1) Sound does not work at all.  No speakers or head phone jack.  Under settings/sound it says Dummy Output.   

I've been through this whole page, and updated the kernal several times.

It seems to find a soundcard. 

>aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC3266 Analog [ALC3266 Analog]

Subdevice #0: subdevice #0

>uname -r

2) The touchpad does not work at all, and I have to use an external mouse all the time. 

3) When connected via the VGA adapter to some VGA projectors the external display is dropped after a few minutes.  It will come back with enough clicking around.  I've used these same projectors just fine with my old 12.04 machine.  

This is all extremely frustrating.  Buying the machine with Ubuntu installed should mean it works with Linux.
