I have read users report large latencies (unable to watch movies) of
hiFace1 in OSX while reportedly they have not identified any major
latency in windows. Perhaps the fixed PCM_PACKET_SIZE
https://github.com/panicking/snd-usb-asyncaudio/blob/master/pcm.c#L25
limiting the period size
https://github.com/panicking/snd-usb-asyncaudio/blob/master/pcm.c#L98
does not have to be a single relatively large value?

Thanks,

Pavel.
