This was always the idea of how this should work. >It seems unecessary to have to set this up though because the devices >are already available to be accessed as hw:0,0 hw:0,1 hw:1,0 ... > >Shouldn't JACK find all available inputs and outputs by default instead >of relying on the user to define the device to be used? > >If not it seems that JACK is missing an extremely lucrative feature >which would contribute greatly to Linux audio and would no doubt peak >the interest of anyone who is not already interested. This isn't a question of JACK's policy, rather its more JACK following ALSA's design. Because ALSA allows the user to define PCM devices, ALSA doesn't currently offer any convenient way of enumerating all the possible PCM devices. If you sit down and think hard about the many situations a user might find themselves in, I think you'll see that the approach of "find all "hw" devices, gang them up, and go" really isn't very helpful. And for those people who try it, they will face the sync problem in nearly every case. >I can hear Paul now saying you have no desire to make this happen >because you do not work with consumer devices. Unless someone paid you >to do it. That's correct. Consumer devices are just that. People trying to do multichannel work by ganging such devices are engaged in a strategy I don't want to support with my own time. >If it is possible to do and the code was written would it be included in >JACK? Its possible, and if it was reasonably written, it would be included in JACK. >If it is possible to do how much would it cost to have it implemented? I don't know. Somebody else would have to do it. --p _______________________________________________________________ Sponsored by: ThinkGeek at http://www.ThinkGeek.com/ _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
