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?

I only know of a script that checks the environment and tries to figure
out whether system settings are sane for pro audio, but I know of no
program to test all possible audio systems.
The idea is good, but I see some potential problems:
- dependencies: would one need to install every sound system to run the
program? I think it would be necessary to discover sound systems at
runtime, which, I guess, is hard, because so few programs do it.
- distribution dependent stuff: I think about paths and stuff. It could
be hard to give sane advise if configuration is different between
distributions.
- relevant non-audio stuff: Non-audio stuff also needs to be taken into
account, for example: recently I talked to someone on IRC who had
trouble with getting jack to run. I talked him through all the typical
things and it still didn't work. It turned out that policykit was at
fault.
It's a good idea but I doubt it's easy to do. Are you a programmer and
have experience with the necessary stuff? To me it looks like a
worthwhile thing and something I'd like to work on during the summer,
but I doubt I could do it alone. This is definitely a team job,
especially because it needs to be tested on various setups.

I think it was someone in #ubuntustudio or #opensourcemusicians who
alerted me to a project I've not tried out just yet by falktx called
cadence
http://repo.or.cz/w/cadence.git
Sounds like it might be what I'm after but won't know until I try.
Anyone beat me to it who can comment on its suitability right now as a
Linux audio diagnostics tool?
