[linux-audio-user] Jack + Alsa routing?

Hello. I'm developing a jack application. The test files are played to the application with aplay and mpg123. How do I route the played audio to my application and then the output to Alsa? Note that aplay plays to the "wave" control in alsamixer. Now my application connects to alsa_pcm:in_1 alsa_pcm:in_2 alsa_pcm:out_1 alsa_pcm:out_2 and it is the same "wave" control. Puzzle: To prevent aplay from going to speakers, I have to turn the "wave" to zero. But then how do I route anything to speakers if my application outputs to the same "wave"? You may freely assume the aplay and mpg123 are not changed in any way. Juhana -- http://music.columbia.edu/mailman/listinfo/linux-graphics-dev for developers of open source graphics software
