Both Windows and macOS have the ability to select a default device for sound output. If audio output via the dock is not working, please ensure that the ‘USB Audio CODEC’ device (which represents the dock’s analog audio output) is set as the default audio playback device. From within macOS this can be done via the Sound application within System Preferences. From within Windows this can be done by following these steps:
- Right-click on the speaker icon in the Task Tray in lower right-hand corner of the desktop (by the clock).
- From the menu that appears, select the ‘Playback devices’ option.
- From the ‘Sound’ window that opens, right-click on the entry that says ‘USB Audio CODEC’ and select ‘Set as default device’.
