## TL;DR

For diarization in live mode, send multi-channel audio with one speaker per channel and track speakers by channel number instead. Speaker diarization has the same restriction, pre-recorded only, it will not run on a live session.

For diarization in live mode, send multi-channel audio with one speaker per channel and track speakers by channel number instead. Only rely on server-side pii_redaction for pre-recorded jobs.

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
