Dear All,

Is there an example code on how to program a full duplex audio transmission?

I did search the internet but it is full of Paul Davis advising to use Jack instead of ALSA.

I think I would rather use ALSA for my purposes.

I've wondered about this myself... perhaps a bit naïve on my part, but how about just creating separate record and playback streams then synchronising them? I'm not certain that JACK is the bee's knees solution either -- otherwise why not have JACK's functionality embedded in the kernel in the first place? :-) -- Stuart Longland (aka Redhatter, VK4MSL) .'''.
