I generally don't need these features. From a user perspective Audio applications should use ALSA. If an application does not use ALSA I will either not use that app, turn off the sound features or figure some other workaround. > * Others will make their application an ALSA application ... > * People who want their application to run on other unixes too > will make their application an OSS application (see the > commercials like real or Skype) This is the only other relevant choice. > There is the example JACK capture client which is a good > starting point for programming newbies. > > > What would really be useful would be some example code in the > ALSA wiki showing how to create an application which is > jackified but even can play and record via an ALSA DMIX > device and optionally has further input/output plugins for > esound, artsd and gstreamer.

I realise that from the POV of non-music-making applications it might look this way, especially if you were bothered about cross-platform portability. I think if you were writing a specific Linux Audio application you would use ALSA. Please excuse me if I'm missing something that would be obvious to a programmer. As a musician and a Linux user I set my machine up to use ALSA and get quite annoyed when other apps launch another sound system in the background and block my soundcard. Actually It bothers me so much that I'm thinking of uninstalling both artsd and esd, but I'm not sure if dependencies will allow this. cheers, tim hall http://glastonburymusic.org.uk
