Forced slowdown in Legend of Legaia hyper arts, items and magic?

[Rumba121]

The issue also occurs in standalone PCSX-ReARMed, even with unai renderer.

Description

Its not a major issue, yet an annoying one. In this game (scus version) while in combat you can execute hyper arts, spirit and magic summoning all appear to have an initial slowdown which desyncs the audio from the image.
¿any idea how to solve this?

Steps to reproduce

Play the game with any renderer open-gl or dispmanx or unai, enter a combat and execute a "Hyper Art", use an Item, cast a Magic or use Spirit.

When did the behavior start?

Always.

Does this still happen ? I believe this is a counting issue just like how some games suffer from this.

Haven't tried lately, (my pi is collecting dust for some months), I will try it probably on next Sunday, and post update. Sorry for the late reply.
