The microphone indicator shows it's off when it's actually on

### What Happened?

When using the microphone and seeing the indicator for the first time, it shows that it's off, when in fact it is active and listening.

### Steps to Reproduce

1. Run ` pkill -f io.elementary.wingpanel.`
2. Join a video call.
3. Open the microphone indicator.
4. Notice that the indicator says the microphone is off.

### Expected Behavior

The microphone indicator should reflect the actual status.

### OS Version

8.x (Early Access)

### Session Type

### Software Version

Latest release (I have run all updates)

### Hardware Info

Start by reproducing the issue in panel-sound with `pkill -f io.elementary.wingpanel.`, then join a video call and inspect the microphone indicator's initial status. Trace how the indicator determines whether the microphone is active, and consider the issue done when it consistently reflects the actual microphone state on the listed Wayland setup.
