Hello,
I'm working on a project where I want to make an audio connection
between two applications. My situation is very similar to Andrew. I
would love to have two sound devices that are coupled so that if I play
sound into one device, I can record it from the other device and vice
versa. Is this possible with ALSA? I've looked at numerous .alsarc
examples but I just can't seem to find and documentation on this subject.
I've read about the snd-aloop driver but that did n
Sorry for hijacking this post but it seemed more relevant to tack on to
it than to start a new topic :)
Kind regards,
Benjamin van den Hout
