Can't hear guitar.ogg on any song (also in tutorial songs)

I have found this in logfile: What is the expected output? What do you see instead? (W) Unable to load guitar track: matrices are not aligned for copy (W) Unable to load rhythm track: matrices are not aligned for copy (D) Song with only a single audio track identified - single-track miss volume applied: 0.9 (D) Retrieving notes from: /media/dokumenty/Hry/FretsOnFire_RF_new/data/songs/metallica/4.10-Welcome Home(Sanitarium)/notes.mid

What version of the product are you using? On what operating system? Ubuntu 9.04 AMD64 Version of fofix: stable and also from svn (non-compiled).

I have tryed to do things like set sound quality to 8bit (it works on original FoF on 64bit system) and so on.

See Issue 650.

It is an issue with your version of Pygame.
