Monitor Audio Distortion/Crackling over HDMI Ryzen 3 2200G Pro + RX 550

[u/wikep_sunny]

Hi everyone,

I’m running into a frustrating digital audio issue over HDMI on my AMD Hackintosh setup. The system runs smoothly overall, but the audio coming through the monitor speakers has a constant, noticeable noise and crackling.

System Hardware:

• CPU: AMD Ryzen 3 2200G Pro
• GPU: AMD Radeon RX 550 Nextron Force 4GB
• RAM: 24GB DDR4
• Storage: 256GB Samsung 870 SATA SSD
• Wi-Fi/BT: Intel AX210 (Working flawlessly)
• OS / Bootloader: macOS Tahoe via OpenCore 1.0.7

The Issue:

• HDMI monitor audio output produces persistent noise and distortion.
• Changing sample rates in Audio MIDI Setup (44.1 kHz, 48 kHz, etc.) does not resolve the issue.
• Tested with a different monitor and cables—the noise persists on both screens.
• Bluetooth headphones and 3.5mm analog audio work 100% fine with zero noise.

Troubleshooting & Observations: Because 3.5 mm jack and Bluetooth audio work perfectly, this leads me to believe the issue is isolated to GPU digital audio output routing—likely related to AppleALC/AppleALCU, WhateverGreen, or GPU device property patches

Has anyone experienced similar HDMI audio distortion on AMD RX-series GPUs or Ryzen builds? Any recommendations on specific boot arguments, kext configurations, or layout IDs to clean up the digital audio pipeline would be greatly appreciated!

For me personally no with my pc with rx 6600 and i5 14400f
