[Jack-Devel] jackd and volume control

As far as I understood there are 3 opinions: 1.) Don't change anything 2.) Add some API-calls to control the volume of every port 3.) Add an API-call to control the volume of system:playback_* I'd say that 2.) will introduce too much complexity. This is what jack clients should do. But some time ago I proposed 3.) - Not every audio adapter has a software controllable hardware mixer, e.g. Focusrite Scarlett Solo, 2i2, 2i4. So alsamixer can't do the job. - No need to break clients' connection to system:playback_* and make connections to a volume control application like jack_mixer. That's really nasty when the application connects only at playback with changing port names, like Audacity. Then you need tools like jack-plumbing. I can live without that but that's what new users would appreciate, especially when there are some apps for the system tray/dock/whatever.
