--- Comment #6 from Arian Wichmann arian.wichmann@gmx.net 2008-12-16 12:12:11 --- There is news regarding this issue.
I have retested the program with the new 2009 version and version 1.1.10 of Wine.
With this I was able to play files. This still locks the gui so that I have to kill the process, but at least the audio engine seems to work.
Adding of files is still not supported.
