Dante Via (Windows): What is Network Throttling?
In order to reserve processor resources for time-sensitive multimedia applications (including Windows audio applications), Windows implements a network bandwidth control called ‘network throttling’, which restricts the processing of non-multimedia network traffic when audio applications are running.
Network throttling can interfere with Dante audio traffic when Windows audio applications are running. For this reason, you can let Dante Via manage the network throttling setting on your PC, to prevent it from interfering with your Dante audio.
If network throttling is configured on your PC, Dante Via will detect it when it is run or installed, and ask you if you would like Dante Via to manage network throttling for you. Changing the setting will require a restart of your PC.
