|
|
| minperiod | The minimum update period in seconds.
|
| defperiod | The default update period in seconds.

Remarks
If none of the BASS_DEVICE_ENABLED, BASS_DEVICE_DISABLED, or BASS_DEVICE_UNPLUGGED flags are present, then the device is not present. That could be because it is an unplugged USB device or it has been disabled in Device Manager, for example.
Depending on the BASS_CONFIG_UNICODE config setting, name and id can be in ANSI or UTF-8 form.
The corresponding BASS (DirectSound) device can be found by its BASS_DEVICEINFO "driver" member matching id.
