Alundra problem

I have a little problem with Alundra (NTSC). Everytime I get a life vessel or major item, the little sound confirming that you get the item goes very slow, and skips a lot. This causes the game to go very slowly for about 3 minutes, and I cannot move. After getting the item and waiting for 3 minutes, everything goes back to normal.

I know this is a small problem, but it would be nice if someone knows how to fix this. The problem is either the emu itself, or the sound plugin. I have tried using every plugin, but it happens to all of them. I even tried it with no sound, and it still happens.
Anyways, not a big problem, but if someone knows how to fix this, it would be much appreciated.

Thanks.
