Alert slider not working on avicii / OnePlus Nord and not changing to different modes

Expected Behavior

When using the alert slider (physical toggle on the device), the toggle should set different modes for the user (normal mode, vibration mode, silent mode etc). The default on OnePlus Nord / avicii is downwards position = normal mode; middle position = vibration mode; up position = silent mode

Current Behavior

When using the alert slider, there is nothing happening and the system doesn't reflect this, i.e. if I set the alert slider to silent mode, the system doesn't reflect this change and I have full sound and vibrations. adb logcat is attached

Device info:

LineageOS version: 21-20240215-NIGHTLY-avicii

Troubleshooting which has been tried:

  • Checked stock OS, the alert slider works as expected. On /e/os 1.19 stable, the alert slider also works.
  • Physically cleaned the toggle from debris and dust.
  • Went through settings -> System -> Buttons -> Other buttons and checked if the settings are correctly put there (they are).
  • Checked the internet forums and found this very old OnePlus community topic. Basically adb root -> adb shell -> settings --cm put secure cm_setup_wizard_completed 1 but there is an error: "Invalid command: --cm".
  • Clean reinstall of LineageOS 21.

Steps to Reproduce

  • Boot the device
  • Wait for booting to finish.
  • Unlock your phone.
  • Change the position of the alert slider physically.
