OK, fair enough. However, if there is no jack running, the option should have no effect so so what? For pulseaudio FUD, it seems that a good part of the linux audio community dislikes pulse and is circulating this message. One probably can live without jack and pulse simply to listen to mp3s and streams. _______________________________________________ pkg-multimedia-maintainers mailing list pkg-multimedia-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/pkg-multimedia-maintainers
