Here are the details that you wanted.
I am using Mac Mini (Intel Processor) running Mac OS X 10.5.7.
I built the executable and tried to play with the application. As part of that exercise, I tried to play a WAV file by importing it. Since
I was not hearing the music, I thought there could be some problem with my build process. So I tried the same procedure on
a pre-built executable and that also failed for me.
Hence I posted this message. I presume this could be some setting problem which I could not figure out. I exported the tracks as
WAV file and played with Quicktime and I was able to listen to the music.
I did not face such a problem on a PPC. There also, I built Ardour from scratch. So I thought it was peculiar to Intel processor.
To build Ardour on OS X, it took approximately 10 hours. There were problems with the build script (python file). Had to fix them to
make a successful build on OS X. The documentation was helpful to get all the dependent libraries. But it was a tedious process.
Let me know if you need any further information.
