I agree with you.
What I plan to do is to allow several hw_params call on the master (first) 
stream until the point when the playback is actually started.
I need to check how does the consequent hw_parmas looks like. Do they retain the 
already configured parameters? What I mean is that at the last hw_parmas call is 
it so that all the needed information sent to the driver?

Thanks,
Péter
