Another observation: The microphone input works perfectly fine with
jackd, too. But if I start pulseaudio, then start and immediately quit
audacity, then stop pulseaudio again and try to start jackd from
qjackctl, qjackctl hangs and I have to force quit it.

I also attach the log output from audacity, the lines around the
"AlsaOpen ... failed" my be relevant.

Title:
  audacity kills rear microphone input on Starship/Matisse HD as soon as
  it starts

Status in audacity package in Ubuntu:
  New

Bug description:
  Scenario:
  =========

  1. A mainboard (Asus Prime 570-Pro) with onboard audio:
  c:00.4 Audio device [0403]: Advanced Micro Devices, Inc. [AMD] Starship/Matisse HD Audio Controller [1022:1487]
          Subsystem: ASUSTeK Computer Inc. Starship/Matisse HD Audio Controller [1043:8733]

  2. The device is configured as Analog Stereo Duplex in pavucontrol
  3. A microphone is plugged into the pink input jack
  4. The VU-meter in the pavucontrol "Input devices" tab displays plausible levels for the mic
  5. The mic works in most applications (mumble, teams)

  Steps to reproduce:
  ===================

  1. Start audacity

  Expected behaviour:
  ===================

  The microphone should continue to work, and Audacity should be able to
  use it

  Observed behaviour:
  ===================

  As soon as audacity starts, the VU-meter in pavucontrol is updated
  only about once a second, and the displayed levels have no discernible
  relation to the levels of noise I make as displayed e.g. for the USB
  Mic in my webcam. If I start to record using the microphone in
  Audacity, audacity records with a speed of maybe 0.25 recorded seconds
  per second of wall clock time, recording only weird sounds, if
  anything at all. The microphone stays unusable for all applications
  until I restart the computer.
