How do I make sure the server is running?
Open Windows Services and look for the Canary HDA Server. By default, the service is set to run only when an HDA client connects to it.
If making a regular connection to the server, it may be helpful to change the startup type to automatic.
Does the server support the Async interfaces?
No, the Canary HDA server does not support this interface. Browsing with the IOPCHDA_SyncRead interface will supply this error message.
