I'm new to Pd as well and ran into the ver same problem. After a bit of guesswork, I tried running Pd with the command: pd -alsa -alsaadd dmix which seems to add an unlabelled audio output in the Pd alsa configuration menu. When this output is selected, it solves the problem. I works well enough, but I haven't tried using jack. Can anyone who has used both dmix and jack offer offer an opinion on the pros and cons of each? .Lewis _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
