Ignore an empty audio frame?

[lplassman]

Hi,
I am using an audio input interface using the ALSA driver that sometimes wakes up the callback when there is no data. Is there a way to test the frame output inside the MiniAudio callback, to see if contains actual data or not?

Thanks!

When you say there is no data, do you mean the frame count is 0? miniaudio will fire the callback whenever ALSA tells it that data is ready to be delivered, using whatever frame count it provides. If the count is 0, just use that, otherwise there's no way to know if it contains valid data or not.
