MacOS: Microphone stays active after stopping a recording until Cap is quit

[bertinlr]

Description

After I finish a recording, the microphone stays active. The macOS mic indicator keeps showing that it's in use until I open Cap and quit it manually. Only then is the microphone released.

Expected behavior: Cap should release the microphone as soon as the recording is stopped.

Note: I have Krisp (notetaker) installed on my MacBook, but Cap is in Krisp's excluded apps list, so Krisp should not be capturing or transcribing anything during Cap recordings.

Reproduction

1. Open Cap and start a recording with the microphone enabled.
2. Stop the recording.
3. Notice the macOS microphone indicator stays active.
4. Open Cap and quit the app.
5. The microphone indicator turns off.

Additional Context

• Cap version: [0.6.0]
• Operating system, version: macOS [27.0]
• Device (optional): MacBook Air M3

Other apps running: Krisp (Cap is added as an excluded app in Krisp)
