Is there any limitation on maximum number of controls we can have.
Not that I'm aware of beyond sizeof() type stuff which you're probably still a way away from.
At least, for USB devices there's a maximum for logical mixer channels (currently, MAX_CHANNELS = 16). This might feel like a limit for the number of mixer controls depending on the respective mixer topoplogy. MAX_CHANNELS can't be raised deliberately in the current code since it is used for some bitshifting. I don't know if something similar exists for PCI devices
