I have the Dell Sputnik xps13 (9333) and I'm currently running Arch Linux on it. Most things work correctly but I'm having issues with the soundcard. Just to note I'm not using pulseaudio at all, only ALSA.
* The internal microphone doesn't work correctly. I set it to "CAPTURE" in alsa mixer but running
$ arecord -d 5 test.wav
$ aplay test.wav
just gives me silence.
The only application that I've managed to record something with is Audacity by manually selecting "HDA Intel PCH: ALC3661Analog (hw0:0) Internal mic:0.
* Occasionally my system will get into a state where plugging in headphones does not work correctly. When I plug the headphones in sound will continue to comes out the speakers and nothing comes out of the headphones. Unfortunately I have not found a reliable way to reproduce this issue.
Here is the output of running the alsa-utils-alsa-info.sh
tarini@tarini-ultrabook:~$ lspci | grep Audio 00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)
I think you have an older sputnik model (1st or 2nd generation) so your problem is completely unrelated to mine. Also the kernel in stock Ubuntu 12.04 is very old (I think it's 3.6 or something like that). I'm using 3.14
I got same problem on webcam using Cheese: webcam led turns on but I've got a black image.
ALSA has nothing to do with the video output, your issue is unrelated to mine or any sound card issue in general.
