In a conversion project of mine, I needed a Linux version of "mmsystem" & therefore discovered Uos.
I liked it because /1 it worked right out of the box, 2/ it is Windows/Linux ready & 3/ it was not a bloated project.
However, I quickly discovered it was not able to play iTunes .m4a's or CD's, of which my project required...
I therefore undertook to add these to my copy of Uos.
I used converted newac headers for 'libfaad' for .m4a's & 'CDRip122.dll' for CD's.
If there is any interest to have this added to Uos, I'd be glad to help. If not, that's ok too.
