Is this possible? Short answer, no. I think there are some very high end audio cards that have more than one processing pipeline, but I have never owned one. With a standard card, this is not possible because the "engine" can only process one stream at a time. The analog output has to go to the output device continuously, so it can't do more than one at a time because there is no time. :-) In other words, to have two sound streams running simultaneously to different outputs, you have to have two sound devices. Jack and pulseaudio solve a different problem; mixing multiple inputs before sending them to the "engine", and routing the output to multiple places. Just buy a cheap USB soundcard (get one that adheres to the standard, or if it doesn't, has been reverse engineered to work in alsa), and you can do what you want. Desktop users can use USB, but also can use a cheap PCI card also. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
