** Description changed:

  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]
+         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 moinse I make as displayed e.g. for the USB
- Mic in my webcam. If I start to record using the microphone in Audacity,
+ 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.
