The DASHStream implementation only outputs audio streams of a single language when --locale is set. And this requires a valid locale string, as shown in the linked code. If no language was set, then the language of the first available audio stream is chosen. Any additional audio streams then get filtered by that language and are then available as alt-streams in the final stream selection. https://github.com/streamlink/streamlink/blame/3.1.1/src/streamlink/stream/dash.py#L205-L242

This is a limitation of the DASHStream that is not ideal and which needs to be improved.
