That's a good idea, but the two patches aren't necessarily exclusive. In an
embedded solution you may want a 2s PCM buffer for low-power playback and a
64k buffer for snd-aloop as it is only used with small periods. Also one
would need to check the buffer/period sizes in each driver, and make sure
they are smaller than this global max.
