[alsa-devel] alsa callback not async

Hi guys,

I am cross posting this because I am not sure which list it belongs to.

I have a test program I wrote to help me learn ALSA APIs, It work to a degree. It is a simple Capture/Playback interface. My problem is that when the Callback starts, it does not allow any cycles back to the main program. The main program waits for console input to tell the callback when to stop. Well it does not accept any console input when the callback is running. Any ideas??
