[LAU] Linux Audio Diagnostics Tool

Hi Linux Audio Land! I've been thinking recently just how useful it would be- certainly to Linux audio distros and (Linux (audio)) newbs, if we had an app that could tell you what sound systems are currently active and let you test them- both audio in and output for ALSA, JACK and Pulse at the very least but FFADO, esound, phonon and whatever else would be great to see included too. Even for a Linux old-timer like me its tough remembering all the different mixers, daemons and diagnostic utils and commands to work out where you are when you have sound trouble. If it can't fix your problems automagically then it would be good if it could advise the user on how to get their desired sound system functional, if not optimised as in the case of JACK as I think that could end up being its own app or should be integrated into qjackctl. JACK gives more useful error messages now which should help in putting something like this together but AFAIK there's nothing out there like this atm. Anyone know of an existing app like this or if work has already begun on such a tool?
