Hi! the sndfile-programs now have a jack enabled play program, but I'm not sure, if libsndfile supports mp3. Then there's ecasound, which can be installed from all major distros as well. It plays mp3 using mpg123 or mpg321 and its own JACK capability. You could be dirty and use a pipe with sndfile-jackplay. Also you can create an ALSA device, that uses JACK and then use sox directly if you like or a concatenation of mpg321 and aplay. The JACK plugin would look something like this, in your ~/.asoundrc or /etc/asoundrc (I think they changed the system wide name some time back): pcm.!default { type plug slave { pcm "myjack" } } pcm.myjack { type jack playback_ports { 0 system:playback_1 1 system:playback_2 } capture_ports { 0 system:capture_1 1 system:capture_1 } } Admittedly, this way you can't use ALSA directly, not with your default output, but I guess, you've got JACK running all the time anyway. :-) Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
