[Stk] RtWvOut and audio device on linux

[Enrico Costanza]

Dear All,

I am trying to use the stk on kubuntu 7.04, and I am experiencing 
problems with the real-time classes.
Here is a simple test program trying to allocate RtWvOut with the 
default parameters, and its output.

---
#include <RtWvOut.h>

using std::cout;
using std::endl;

int main(){
    RtWvOut * test = NULL;
    cout << "about to alloc" << endl;
    test = new RtWvOut(  );
    cout << "allocated" << endl;
    delete test;
    cout << "de-allocated" << endl;
   
    return 0;
}
---
This is what I get:
---
about to alloc

RtApi: no devices found for given stream parameters:
    RtApiAlsa: channels (1) not supported by device (hw:I82801CAICH3,0).
    RtApiAlsa: pcm device (hw:I82801CAICH3,1) won't open: No such file 
or directory.
    RtApiAlsa: pcm device (hw:U0x4710x329,0) won't open: No such file or 
directory.

At the same time, audio seems to work fine on my machine.  For example I 
can play wave files with aplay.
Am I doing something obviously stupid?

Any suggestions and pointers are welcome.

Thank you in advance.
