LED Microphone Mute issues with different Kernel versions

[MaMicha]

@nikgnomic

The LED appears to be working, but not as expected

amixer -c2 sset 'Capture' nocap - audio capture [off] - LED turns OFF
amixer -c2 sset 'Capture' cap - audio capture [on] - LED turns ON

I fully agree!

@nikgnomic

I suspect that when you mention Mic being muted and unmuted, this is referring to the ALSA playback control Mic for monitoring microphone audio

To be honest, I’m totally confused about ALSA pipewire and Co.! What I’ve checked in the past:

• The MIC-symbol in System section of the control bar > Volume > MIC indicates the actual state; I can toggle it there.
• This is the same state as in SystemSettings > Audio > Mic.
• In some cases I checked the (UN-)mute state using AUDACITY, in each case it was correct.

I’ve seen the MIC-Mute-LED working properly this week using an actual KDE-neon (VirtualBox).

If you can find the ALSA settings from the VM …[/quote]
Running KDEneon again, I found this:

• KDEneon System:
  • Operating System: KDE neon 5.22
  • KDE Plasma Version: 5.22.4
  • KDE Frameworks Version: 5.84.0
  • Qt Version: 5.15.3
  • Kernel Version: 5.11.0-25-generic (64-bit)
• System section of the control bar of the MANJARO-System gets changed: After LogIn to KDEneon with MIC-symbol, without KDEneon NO MIC-Symbol (ref. screenshots, without NEON first, with NEON second).
  

• If the MIC-Symbl is available (e.g. NEON running), UNmute / mute can be switched by clicking that symbol. The F4-LED indicates the actual state correct.

If you can find the ALSA settings from the VM and replicate them in Manjaro it should work the same

Both version of /var/lib/alsa/asound.state are ready for download.
