So, it's natural to send in this size. It's no > requirement but a common use case. Thus, is it possible to buffer the data in ALSA before sending them to the driver, in such a way, that the driver always receives period_size samples, regardless of what the application sends to ALSA? And how would I configure ALSA for such a setup?
