Bad sound quality with SDL_Mixer

Hi,

I am currently trying to replace sound playback done via SDL in an old game
(Descent 2 mod D2X-XL) with calls to SDL_Mixer functions. This is working so
far, but sound quality is greatly decreased - reverb and higher frequencies seem
to be missing, everything sounds like played inside a tin can. The chosen audio
format (AUDIO_U8) is the proper one though. Any hints of what I need to
add/tweak here?

Problem solved - the sound data was mono, all I had to do was to duplicate it to
two channels.
