Windows ASIO versus WDM
On Windows systems, ASIO and WDM are different subsystems that are configured and
operated separately. ASIO is typically used for DAW setups, while WDM is typically used
for system sound I/O.
ASIO system settings are configured in the Apollo Solo USB Console Settings>Hardware
panel and within the DAW preferences. WDM system settings are configured in the
Sound control panel within the Windows OS.
Important: When using Apollo Solo USB for WDM system sound I/O, the
sample rate of both subsystems must be set the same rate to be heard in both
subsystems. See Windows WDM System Sound Notes for related information.
