Video demonstration of the bug

SUMMARY

Clicking the microphone indicator widget with the left mouse button (LMB) can only mute the microphone, but cannot unmute it. To re-enable the microphone, the user must use the right mouse button (RMB) to open the context menu, then open the "Mute" submenu. Surprisingly, the mute checkbox is not enabled, even though the microphone is muted. To unmute the microphone, the user must check the box manually, then reopen the menu and uncheck it. Only after this sequence does the microphone turn back on.

STEPS TO REPRODUCE

1. Click the microphone indicator widget with LMB — the microphone gets muted.
2. Click again with LMB — nothing happens, the mic stays muted.
3. Right-click (RMB) on the same widget.
4. Open the "Mute" submenu — the checkbox is not checked, even though the mic is muted.
5. Manually check the box.
6. Close the menu and open it again via RMB.
7. Uncheck the box — only then does the microphone become enabled again.

OBSERVED RESULT

The microphone can be muted via LMB, but cannot be unmuted the same way. The "Mute" checkbox appears unchecked, even though the mic is actually muted.

EXPECTED RESULT

Clicking the widget with LMB again should unmute the microphone. Also, the mute checkbox should be visibly checked when the mic is muted.

ADDITIONAL INFORMATION

Would it be possible to replace the muted microphone icon in the widget with the one shown in the "Mute" menu when accessed via right-click? That icon more clearly indicates that the microphone is muted and is visually more noticeable than the current one.
