Release ASIO Driver in Background
This Cubase/Nuendo option can be found the menu Devices > Device Setup... > VST Audiosystem (older versions: VST Audiobay, VST Multitrack) and is used to release the selected ASIO driver when another program comes to the fore.
This can necessary when the ASIO driver is not "multi-client" capable but you want to use your audio hardware with another application beside Cubase/Nuendo.
- When you start an audio export the ASIO driver is used. When the option "Release ASIO Driver in Background" is enabled you should not put another program into the foreground during the export. Otherwise the export could fail or even cause crashes.
- If you connect other programs (for example Reason) via ReWire with Cubase/Nuendo the option should be disabled in order to allow a stable ReWire connection.
Generally it is recommended to enable the option only when required.
If you don´t hear any audio output in Cubase/Nuendo after switching applications please use the button "Reset" on the bottom right in the menu Devices > Device Setup... > VST Audiosystem (older versions: VST Audiobay, VST Multitrack).
