[Stk] Problem with channelsOut in FileLoop

[Fabián Tommasini]

Hi,
I'm trying to know the number of channels in a file that is playing 
through FileLoop. But, some errors appear:

/usr/include/stk/WvIn.h: In member function ‘bool InputWaveLoop::load()’:
/usr/include/stk/WvIn.h:23: error: ‘unsigned int 
stk::WvIn::channelsOut() const’ is inaccessible
input.cpp:75: error: within this context
input.cpp:75: error: ‘stk::WvIn’ is not an accessible base of 
‘stk::FileLoop’

This do not occurs with FileWvIn. Why? How can I solve the problem?
Thanks in advance.
