Windows DirectSound Microphone Gain Control seems inoperative

[JohnColket]

Bug description

Audacity's Microphone Gain Control (Windows DirectSound) does not initially move and cannot be used to adjust the gain on my Laptop built-in microphone. This is a regression over 3.0.5.

This error was initially reported by forum user Pnokio, in this post: https://forum.audacityteam.org/viewtopic.php?p=460750#p460750

Steps to reproduce

1. Tools > Reset Configuration
2. Audio Setup > Host > Windows DirectSound
3. Manually move recording Meter Level control to 100%
4. Exit Audacity
5. Restart Audacity
6. Record

Expected behavior

Audacity's microphone gain control can be used to adjust the incoming recorded level.

Actual behavior

Audacity's microphone gain control is STUCK, and will not move.

If I RESTART the recording, it is movable, BUT, it has NO EFFECT on the recorded audio.

This is a regression on 3.0.5 where the Audacity control moved in lock-step with the Windows control in mmsys.cpl.

Audacity Version

Testing on W10 with 3.2.2

At first I thought that this was working for me when I was just recording
a) The mic slider could be moved wile recording
b) The Microsoft Sounds mic array shadowed the mic slider position

But then I tried monitoring without recording
c) to start with the mic slider moved and the Microsoft Sounds mic array shadowed the mic slider position
d) after a short while the Audacity mic slide jumped to the right 100%
e) the Microsoft Sounds mic slider could still be moved to control the input level

This does not seem to afflict the other two Windows hosts: MME ans WASAPI

Update

What I'm finding odd about this is that while the Audacity and Microsoft Mic sliders appear to be ganged together, moving in unison, the two Playback sliders appear to be totally independent. Is this intentional by design in Audacity?

I was able to reproduce this one on Windows 11

Closing as not planned to be fixed since DirectSound support will be deprecated in future releases anyway.
