Codex Micro “Push to talk” action does nothing, although the physical key works

Description

I’m using a Codex Micro with the ChatGPT desktop app on macOS.

Environment

• ChatGPT app version: 26.715.72359 (build 5718)

• Codex Micro: Connected

• Input Monitoring: Granted

• Microphone permission for ChatGPT: Enabled

• Selected microphone: Elgato Wave:3

• Mic key action: Push to talk

Expected behavior

Holding the Mic key should start recording and show the sea-green lighting animation. Double-tapping should keep recording.

Actual behavior

Holding or double-tapping the Mic key does nothing. Recording does not start, and there is no lighting change.

Troubleshooting completed

1. Confirmed the Elgato Wave:3 works and shows input activity in macOS.

2. Selected the Wave:3 under ChatGPT Settings → Voice → Microphone.

3. Confirmed ChatGPT has macOS microphone permission.

4. Confirmed Codex Micro Input Monitoring is granted.

5. Confirmed the device is connected and other Codex Micro keys work.

6. Configured ChatGPT’s Toggle Dictation shortcut; dictation works through that shortcut.

7. Confirmed the Mic key is assigned to Push to talk.

8. Remapped the same physical Mic key to another action; that action worked. This confirms the physical switch and key event are functional.

9. Restored the Mic key to Push to talk, but it still produces no response or lighting change.

This appears specific to the Codex Micro Push to talk action rather than the microphone, permissions, connection, or physical key
