Denis, (Sorry the last email got sent before I was complete do to firefox crashing!) so I will redo it below:
The target architecture is a Xscale (Intel's ARM) (PXA270). The compiler is GCC 4.1.1, we (Rich and I) tried with floats enabled and the audio quality got even worse to the point were there was NO discernible sound just noise. We have compiled many packages with our cross-compiler and have had no issues. I'm not sure what could be incorrect with the compiler but if you have some suggestions or tests we would certainly be willing to try them.
