Description
What version of the Codex App are you using (From “About Codex” dialog)?
26.901.51231 (build 8109), Codex within the ChatGPT desktop app
What subscription do you have?
Pro; $200
What platform is your computer?
Darwin 25.6.0 arm64 arm
What issue are you seeing?
Starting voice chat in a side conversation fails. Text chat remains functional.
The app logs recorded the following error on three attempts:
“Error starting realtime voice: no rollout found for thread id 01a07ee7-835b-7101-b0f2-5672abefa133”
The avatar-overlay-realtime component also reports:
“Failed to start realtime in the avatar overlay”
Error code: -32600
Observed timestamps:

The error suggests a conversation/session lookup failure. The underlying cause has not been confirmed.
What steps can reproduce the bug?
- Open an existing Codex task in the macOS desktop app.
- Open a side conversation associated with that task.
- Exchange text messages successfully.
- Attempt to start voice chat.
- Voice fails to start. Retrying produces the same error.
Affected side-conversation ID:
01a07ee7-835b-7101-b0f2-5672abefa133
Whether voice works in the parent task has not yet been verified.
What is the expected behavior?
Voice should start in the selected side conversation. If side conversations do not support voice, the app should clearly explain that limitation instead of offering a control that fails with an internal session lookup error.

Research direction
Start by reproducing the failure in an existing Codex task's side conversation on the macOS desktop app, then inspect the app logs for the reported rollout and realtime voice errors. Done means voice starts in the selected side conversation, or the app clearly explains that side conversations do not support voice instead of exposing a failing control.
