Help with amiga 1200 sound being more quest than original

[mark25810]

Hi there i have a 1200 and thought id also use the amiga amulator on recalbox amiberry i think it is

But ive noticed the sound in games is not as good or load, to get it to be as loud as the proper amiga i need turn the vol.up but then it sounds crackly

Is there a way to get it to sound amazing like the amiga
