Starfire Kylie Edition 0918 - Mic fades when others talking, Audio only shows Adaptive Volume

Hi,

Starfire Kylie Edition 0918 mic issue:

- Hey Meta works fine

- Alone in quiet room = clear

- Room with people talking = my voice fades out and back in

- Phone calls people cannot hear me when there is background chatter

Checked:

- App shows Connected and latest

- Device settings > Audio only shows Adaptive Volume, no Microphone adjustment or Voice Isolation

- Tried restart, re-pair Bluetooth, toggle Hey Meta off/on

- Adaptive Volume off still fades

Is this known crowd suppression bug for Starfire? Workaround until mic toggle added?

Build: Starfire Kylie Edition 0918

App: latest

Repro: 100 percent - clear alone, fades with background chatter
