Hi all, First of all, please accept my apologies for cross-posting. I simply feel that this issue may be of interest to all these groups. After some research and experimenting with jacklaunch (libjackasyn) as well as alsa .asoundrc jack plugin I found out that very few apps actually cooperate with either of these. Jack plugin for asoundrc practically works only with aplay/arecord and freebirth. Audacity doesn't cooperate with either, while jacklaunch even though it has been reported to work with sweep doesn't on my machines (mdk 10.0 and 10.1). I've tested latest jack, sweep, Alsa 1.0.6 and 1.0.7 (I did not go beyond that as 1.0.8 has apparent issues with hdsploader) and had no luck whatsoever. Hence, I am just wondering at this point whether asoundrc jack is still in the testing phase (some of the errors that apps reported trying to use jack plug were due to inability to probe some info from the alsa driver which implies possible incompleteness of the implementation or weird probing from the app's side) and also whether anyone has had better luck than myself using either of these with audacity, sweep, and other non-jackified, yet important Linux audio apps via either of the aforementioned ways. FWIW, it would be really nice to see some united effort to jackify some of the other critical Linux audio apps even if their original authors do not feel like that is one of their priorities (I know, I know, if I am so interested in such developments then I might as well set an example by doing what I am advocating, which is something I would love to do, but unfortunately currently the notion of "free time" in my life is but a joke).
