Voice fails to connect after reinstall on Windows

[mjferdinandus-debug]

What issue are you seeing?

Codex Voice no longer starts because it refuses to establish a connection.

Context

• The Codex app was reinstalled after repeated computer freezes/restarts.
• Codex worked again after the reinstall, but Voice subsequently stopped connecting.
• Windows may change the default microphone and speaker after a restart; the intended devices were selected again.
• Restarting Codex did not restore Voice connectivity.

Expected behavior

Codex Voice should connect and use the selected Windows microphone and speaker.

Additional information

The exact error message and app version were not available at the time of filing.

Diagnostic update: Bluetooth media routing restored on Android

I found and resolved a closely related audio-routing symptom on my Samsung Galaxy A33 with a connected Bose SoundLink Revolve II.

The Bluetooth connection itself was active, but media/voice audio continued to play through the phone. The working sequence was:

1. Open Media output on the Samsung phone.
2. Open the media-session controls shown there.
3. Tap Resume and then the Play button.
4. Android reactivated the media session and routed the sound to the connected Bose speaker.

The apparent chain was:

Bluetooth connected → media session inactive/paused → Android kept audio on the phone → Resume/Play reactivated the session → output routing switched to the Bose speaker.

This points to a media-session/output-routing state, rather than a Bluetooth codec problem. A codec such as SBC or AAC handles the audio stream after routing is active; it does not itself select the output device.

This may help other users who see a connected Bluetooth speaker but still hear audio from the phone.

Important: this workaround was confirmed on Android. It does not yet prove that the separate Windows Codex Voice connection failure described in this issue is resolved, so I am leaving the Windows issue open until that behavior is retested.
