@Zonov, currently you need to switch manually to headphones using this
command:

pactl set-sink-port @DEFAULT_SINK@ "[Out] Headphones"

This requires pulseaudio-utils package to be installed, which it isn't
be default.

The reason for this is that Nexus 10 uses a different jack detection
interface than the other devices. We currently do not support that
interface in PulseAudio.

Title:
  Audio on manta/Nexus 10 non-functional on Ubuntu touch.

Status in “alsa-lib” package in Ubuntu:
  Fix Released
Status in “pulseaudio” package in Ubuntu:
  Fix Released

Bug description:
   affects ubuntu/linux-manta

   affects ubuntu/pulseaudio

  I'm filing against the kernel for manta and pulse, because I am not
  entirely sure where the problem may lie, although based on the logs
  I've been able to gather, I suspect the kernel moreso than Pulse
  itself.

  I'm unable to hear audio either via the internal speakers or the
  headphone jack when either using paplay on the command-line, or using
  the music app. In addition, the music app doesn't update the playing
  position in the UI. I'm using flac files to test with, and I have
  verified that the UI works as expected on the nexus 7, where audio
  works without issue. Eventually, the music player appears to stop
  playing the file as if it were finished, even though no other UI
  updates of track position are shown.

  I have attached 2 logs, one with the sink set to the manta-i2s card,
  and the other with the output set to the manta-spdif card. Incidentaly
  the spdif device is being chosen as the default device after a fresh
  image flash, but thats not relevant here. These logs were obtained by
  following the procedure at https://wiki.ubuntu.com/PulseAudio/Log,
  with the addition of disabling the pulseaudio user session upstart
  job.

  Here are the details from system-image-cli -i re the build number and
  channel, although its worth noting that I have experienced this bug on
  standard daily images as well.

  phablet@ubuntu-phablet:~$ sudo system-image-cli -i
  current build number: 42
  device name: manta
  channel: daily-proposed
