A question about the implementation of notification messages (name, endpoint and function blocks) The spec defines that these notification only get sent upon receiving a Discovery message. Does this mean that the ALSA driver will poll at specific intervals to send a discover message or can the device send a notification even without a discovery message from the ALSA driver ? I could imagine a function block info / name, or endpoint info/ name or endpoint info change (i.e when the device changes the number of function block)
