Audio issue with Ryzen 5 3400G on MSI mobo

[cgla]

First time of AMD OSX build for music, everything works well with proper audio output( onboard headphone, HDMI etc) except the crackling sounds, Crackling sound getting worse when using Garageband with midi keyboard. It is mainly built for a teenager to learn music production, but due to the crackling sound, it is not usable.

Gurus, Any sugguestions?

Thanks,

• OpenCore 0.6.4 with boot arg alcid=7.
• Processor: AMD Ryzen 5 3400G
• Motherboard: MSI B450 Pro M2 Max
• VGA card: Gigabyte Radeon RX570 4 GB
• RAM: 16 GB

This is a known issue with APUs, though there is a workaround: https://github.com/astrihale/speedkeeper
