hi there and thx to everyone supporting this programm.

i just installed it (kubuntu 12.04), it works great but i have no sound at all (tried different games).
i found some hints thx to google. so i downloaded the libMaiAT3PlusDecoder script (from karen angelxwind) and "maked" it. i got the library but strangely not as noted with an "so" after the dot at the end but just an "a". and this one neither works in the lib folder nor in the folder where ppssppsdl is located. i tried to rename it but this also doesnt work.
any idea where to start?

thx in advance! :-)
