Time, endless short time

KISS.
We have all heard of this principle, we try to use whenever we can.
There are tons of books about programming that use this principle - XP KISS system design, KISS code, which is easy-readable.

I have spent about 3 hours fighting with Ubuntu sound systems. I have discovered that there are several different sound servers/systems/modules that do use sound devices on different level of abstraction and HAVE NO COMMON INTERFACES.

Know what? My sound disappeared: I could not call with skype, I could not listen to music; no sound at all. I tried to revert to the original configuration, back and force - no sound at all.

And know what the problem was? My pcm device was muted in the mixer. I spent few minutes checking and fixing that. And three hours finding out what the hell is going on.

So, KISS.
