But inside that directory there should be a subdirectory Phonon.
For example the path for AudioOutput for me (Debian, system dev package) is

/usr/include/phonon/Phonon/AudioOutput

Like Qt itself, most Qt based libraries have two kinds of headers:
* all-lower case variants, with -.h suffix
* camel case variants, wihout any extension.

They are both functionally equivalent (well, one includes the other) and it is 
mostly a matter of style which one is used.
Most developers prefer the camel case variant since it matches the actual 
class name, mostly even including namespace.

Phonon::AudioOutput -> Phonon/AudioOutput.

I am as well. The install procedure should have also installed the camel case 
variant.

So you have phonon/AudioOutput? I.e. the subdir all lowercase but the class 
name camel case?

Cheers,
