I been working a bit on the VHBL and trying to solve some problems that Some Homebrew are having with it. In the progress i got some homebrew to work better with it and reduce the amount of Homebrew crashing with it. I got to the point that i got GWP to load and start up instead of crashing like it did before. My problem is that it give a "can't start Audio Thread" error <- That GWP. I try to load the sample mp3 program and that also gave me an error with sceMp3Init. I found this weird so i tried to load the mp3 example without the sc3 exploit but i still got that same error.
Anyone knows from what may be the cause of that. I don't think it the file since the psp in xmb can load the mp3 file fine and the name of the file and the path is correct so i don't get why sceMp3Init will cause an error running directly from xmb.
Any help will be appreciated.
The code is the sample that comes with sdk. Here the code:
