Can I lock my fps at 30 without the audio slowing down?

My laptop is old and sucks, it doesn't even have Bluetooth. I wanna play Persona 4 but every time I get into battles my framerate drops immensely and all I can hear is a VERY slowed down version of the battle theme. Is it possible to lock the game at 30fps and play without the music slowing down to match the lower frame rate?

no.
50% fps will mean 50% gameplay speed
