Low FPS and Auxio crack loop in Demon´s Souls

Sometimes it drops from 60 fps to 20 and a few, and what is worse, the audio always cracks, it gets a repetitive tone a few seconds after playing that there is no one to remove it (except if they kill me and I am reborn, which is then removed for about 3 or 4 seconds). I don't know what to do and with my team it shouldn't go as bad as it goes:

Ryzen 5 3600 (6 cores)
16 GB Ram DDR4
Placa MSI B450 Tomahawk MAx
Gráfica AMD Radeon RX 5700 XT


I'm desperate!!

This is my configuration and here are the errors it gives me:
