Since upgrading to 15.04, I still experience inconsistent behaviour in
the sound system. Sometimes, the system does not detect the speakers at
all on boot-up. At other times, the Sound panel shows the HDMI sound in
the Settings for Speakers section (although this can be corrected by
clicking on the Speakers in the Play Sound Through box.

Currently (under 15.04), plugging in headphones no longer brings up the
dialogue box requesting to know what device was plugged into the
headphone socket (Stereo Headphones, Headset with microphone or
microphone alone). The Headphones appear in the Play Sound Through
listing and disappear when the headphones are removed. The sound is
directed from the speakers to the headphones if the latter are plugged
in. However, now (under 15.04) it is possible to select the Speakers for
the sound output even when the headphones are plugged in. This was
certainly not the case under 14.10 where the headphones had priority as
though the headphone socket was hard wired.

I have just tried plugging a mono microphone in the headphone socket.
This causes the headphones to appear in the Play Sound Through box.
Unfortunately, the sound has now gone crackly and is not responding to a
change of volume control keys. A reboot seems to be called for.

When playing sound from a Video (using the Videos app), the sound can
become crackly although it can be restored to normal by exercising the
volume control keys (F11 & F12) up and down. If this fails and the sound
disappears altogether, it is necessary to reboot although this does not
work every time and several reboots are required to restore the sound to
normal.

If I use the Volume Control app's Configuration tab to set the Built-in
Audio option to Off, the Speakers in the Sound app show Settings for
HDMI / DisplayPort Mode as Digital Stereo (HDMI) Output. By clicking on
the Speakers in the Play Sound Through box, the Settings for Speakers
are restored with the Test Sound button appearing. The Built-in Audio
Profile changes from Off to Analogue Stereo Output.

Title:
  [XPS13 9333, Realtek ALC3661, Speaker, Internal] fails after a while

Status in alsa-driver package in Ubuntu:
  New

Bug description:
  When playing a video via the Videos app, the sound through the
  internal speakers develops crackles and sometimes disappears
  completely.

  I collected the data for the bug report at the instance that the sound
  had failed.

  Using the Sound panel in Systems Settings to test the sound produces
  no response.

  I have also selected the Volume Control app and attempted to switch
  the sound using the Configuration tab and switching the built-in audio
  between Off and Analogue Stereo Output. Sometimes this works and
  sometimes is does not.

  Having left the Videos app running whist typing this, I have noticed
  that the sound seems to start and stop whilst typing via the keyboard.

  I note that the Playback tab in the Volume Control window shows that
  the sound is being produced by the Videos app (the lower ribbon moves
  with the sound amplitude).

  This bug might be associated with intermittent recognition of the
  hardware on startup. The Sound window sometimes shows no audio device.
  At other times, the speakers are given the HDMI menu dropdown but this
  can be corrected by plugging in a pair of headphones and switching
  back to the speakers which then show the correct Test Sound legend.

  I have noticed several instances of the sound cutting out and cutting
  back in whilst typing this report as if the interrupts from the
  keyboard strokes are interrupting the sound connection.
