Public bug reported: 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 moinse 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.
