I have an XPS 15 and can confirm the audio jack only works once with 15.10—once you unplug, audio is borked. I haven't tried 16.04 yet. Webcam and audio in also

I have an XPS 15 and can confirm the audio jack only works once with 15.10—once you unplug, audio is borked. I haven't tried 16.04 yet. Webcam and audio in also doesn't work, but everything else does (!). I initially tried linux mint, but the kernel was ancient, so latest ubuntu with `apt-get install cinnamon` is roughly the mint desktop experience with more recent packages.
