I have a Dell XPS13 9333 running Ubuntu 12.04. Speakers are working ok, while there are issues using headphones. Headphone are muted when there is no audio playing (that's ok), than when the audio starts playing (for example, a skype message arrives...but that is true for all kind of audio) I can hear a loud wave sound like in non tuned radios, which goes off a little bit later the audio stops playing.

Typing in terminal

sudo aplay -l

I get

card 0: MID [HDA Intel MID], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 0: ALC668 Analog [ALC668 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Can you help me?

I've got the same problem with the developer edition of the 9333, and the whole point of that computer is that it's supposed to work properly with ubuntu! –  Anake Apr 29 '14 at 10:38
@Anake, I know, this is very annoying. This model has various issues (ex.: the coil whine problem) –  Matteo Catena Apr 30 '14 at 10:59
I tried changing from pulse audio to alsa, installing the newest realtek drivers and tried using 14.04. Nothing helped, I've actually requested a return now. Think it's disgraceful that Dell could market it as a Ubuntu laptop when it has problems like this –  Anake Apr 30 '14 at 13:30
