Hm, no idea what the problem can be, so here's a couple of general questions:

- What output plugin are you using?
- Is cmus the only program you are experiencing this problem with?
- Is it working OK when you are not using your digital output?
- What do you do to use your digital output in cmus?

Ubuntu uses PulseAudio by default, and cmus 2.2.0 is really ancient and is
known to have issues with PA. You can try to install cmus 2.3.1, or even the
git version (it is very stable). Unfortunately, there are no ready-made debs,
but cmus is really easy to build from source.

Yes, probably libmad (for mp3's).

Well, now its possible to add my music, but still no output, and
starting it with root shows me:

There should be absolutely no reason to run cmus as root, and the behaviour of
sudoed cmus should be identical to that of normal one (unless you have some
very weird system configuration which I assume is not the case).

Can you ./configure cmus with DEBUG=2, and send ~/cmus-debug.txt files for
both cases (root and non-root)? I hope they can help decrypt what's going on.

This looks perfectly normal, my log is almost exactly the same.

And this is weird. And I don't know how we can get any futher debugging info.

Frankly, I have no idea what's going wrong in either case. Sorry :-(
