This post reveals a new version of the BennuGD port for PlayStation 2 by Masteries.
-Replaces the horrible SDL_mixer port by a heavy modification of Cosmito mixer
-Now, audio mixing is performed via hardware at SPU2 processor
-Lets up to 16 mixing channels at 48KHz Stereo sound
-The audio mixer is capable to perform 12, 24 or 48 KHz sample frequency mixing
-Stereo and mono audio samples can be used together
-Tested on a real PlayStation 2, now the sound is clear.
There are some lack features, like volume change feature, I hope I can fix these as soon as possible.
This link provides an example of this new port version, it is ready to be used in an USB memory stick root:https://mega.co.nz/#!qoxEiKIB!1f-duSm9jpmxyiIeOoo4a0PNKyj0VQ3yx9l86_3DWEQ
