When calling microphone.sound_level(), the code should not register a listener on the CODAL message bus. That's not required and is keeping the microphone LED on.

Yes, the CODAL_STREAM_IDLE_TIMEOUT_MS was implemented in https://github.com/lancaster-university/codal-core/commit/a1e1db692909a260ab341c89b292e085daecd259 and it's currently set to 75 ms: lancaster-university/codal-core/inc/core/CodalConfig.h#L224
