When pluggin in a microphone, the Unknown Audio Device window pops up
and the microphone can be selected. The Microphone - built-in Audio menu
items appears in the System Settings > Sound > Input window as expected
and any sound picked up by the microphone shows up as a moving segment
in the Input level display. The input can be switched to the Internal
Microphone and this shows an appropriate Input Level on the display.

What also happens is that a Headset Microphone item appears in the Input
list as well as Headphones item in the Output list. The sound output can
still be directed through the Speakers (which is not the case when a
pair of headphones is plugged in and identified as the presence of these
headphone prevents sound being sent to the speakers). This, of course,
verifies that the sound output is under the control of the software.

This behaviour is therefore inconsistent with the selection made of the
Unknown Audio Device.

When connecting a pair of Bluetooth headphones, their menu item appears
in the Output window and the mode can be selected between High Fidelity
Playback (A2DP) or Telephony Duplex (HSP/HFP). However, when in the
Telephony Duplex mode, one might have expected the headset's built-in
microphone to appear in the Input window. The microphone works when the
headphones are connected to a mobile phone which automatically switches
the mode from A2DP to Telephony Duplex when making or receiving a
telephone call. It is reasonable to expect the Bluetooth headphones'
microphone to be available to the Sound System for use with video call
apps for which the Dell XPS13 is equipped by having a built-in webcam
and internal microphones.

Title:
  Sound panel in System Settings fails to recognise built-in audio

Status in unity-control-center package in Ubuntu:
  New

Bug description:
  When the system starts up, the sound system sometimes fails to
  recognise the sound hardware correctly.

  One instance is where the System Settings > Sound window shows the
  Speakers, Built-in Audio in the Play Sound Through window but shows
  the settings for HDMI / Display Port instead. It is necessary to click
  on the Speakers in order to get the correct Settings for Speakers to
  be displayed.

  What the System Settings needs is a link to PulseAudio Volume Control
  which provides more options for selecting the various sound channels
  and options available e.g. Speakers, HDMI / Display Port or Bluetooth.
  This app is not necessarily known to the uninitiated. Perhaps some of
  its functionality needs to be included in the Sound window selected
  from System Settings.
