I don't know if this is a bug or what, but I couldn't find anything on the wiki about it.
When I try and play a file that has a sample rate less than 44khz, the music simply doesn't play.
I have no problem however playing files that ARE at 44khz sample rate.
Start of layout -> Play music from file
The files are in .mp3 format and none of my media players have a problem playing the files (WMP, Foobar2000)
Just about to try converting the files into a 44khz sample rate.
Converting it did the trick, it is also now a .WAV file
Should I post this again in bug reports?
