AppleALC borks graphics acceleration & causes extreme boot delay #2392

Closed VisualEhrmanntraut closed 3 months ago

macOS Version: 12.7.4 Audio codec: ALC221 GPU: Intel HD 4600 CPU: Intel i5-4570 HDEF is 0x8C208086 HDAU is 0x0C0C8086

After waiting around 30s on the Apple logo stuck at ~40%, it will boot with only the framebuffer active (no accelerator attached). Disabling AppleALC remedies this.
