On macOS, input gain (input volume) cannot be adjusted for external audio devices through the system sound settings.
When using a RØDE USB audio interface, such as the RØDECaster series, all input level adjustments must be made directly on the device itself.
How Input Levels Work on macOS
- macOS does not provide input gain control for external USB audio interfaces
- System input sliders may appear, but they are not functional for these devices
- All gain adjustments must be made using the hardware controls on the RØDECaster
Behaviour in Third-Party Applications
- Some applications (e.g. Zoom) may display an input volume slider
- This slider may appear adjustable but will typically snap back to 100%
- This is expected behaviour due to macOS limitations
Note:
- This behaviour is standard across macOS and applies to all compatible USB audio interfaces
- If you require per-application volume control, third-party macOS software may provide additional functionality
