Hi,

You can use mixerGetNumDevs function that retrieves the number of mixer devices present in the system. And then mixerGetDevCaps to determine a mixer device capabilities.

Declare INTEGER mixerGetNumDevs in WinMM && Returns the number of mixer devices or zero if no mixer devices are available.

Declare INTEGER mixerGetDevCaps in WinMM INTEGER, STRING@, INTEGER

Best regards.
