Originally, verbs were mapped 1:1 with cards, however Jaroslav recently added support for multiple cards per verb.
Does this mean for a given verb UCM will return a list of devices on different cards that can be used, and the application will choose from the list?
UCM does return the appropriate sink and source PCM device for the given use case if required. e.g the OMAP4 has multiple PCM devices, some are for high quality hifi whilst others are lower power tones.
Or are these multiple cards supposed to be used simultaneously? I probably need more expresso here..
It's to allow multiple cards to be used simultaneously, e.g. a use case could also involve aspects of two sound cards, maybe one for capture and the other for playback.
