JPCSP for Dummies

[Luin]

Hello again,

This time I'm using 3428 and tested it with Zero no Kiseki as well as other games.
I am still not getting any BGM although sound effect and voice clips are working. I have checked Use Media Engine and Decode Audio Files.
I have followed all the steps in main page, putting atrac3pluswav as well as atracplug.dll where they should be.

Edit: Just like before, I suddenly get BGM after finishing a battle, but it only lasts until the next battle or a new music is supposed to play.

If I check extract media files, the emulator does extract the bgm files as .at3, .oma and .wav. Does this mean that the emulator somehow could extract and convert but unable to play?

Just to cover all possible causes,
Could it be caused by wrong install location of the Sonic Stage?
Could it be that I have to specify the path to the Sonic Stage in one of the emulator's bat file?
Could it be that I have to run the Sonic Stage before running the emulator?

Thanks in advance.

Edit 2: Here's the INFO log which should show the BGM playing after battle but stopping once another battle started.
