ok, then that's a miss in your patch1. 320 samples is a multiple of 1ms 
for 48kHz rates. I think it was valid only for the 16kHz VoIP paths used 
in some versions of Android, but that we don't support in the upstream code.

To build on Takashi's answer, the real ask here is to require that the 
period be a multiple of 1ms, because that's the fundamental 
design/limitation of firmware. It doesn't matter if it's 48, 96, 192, 
240, 480, 960 samples.
