Fixes internal speaker support on iMac12,2 27" with Cirrus Logic CS4206 codec (0x10134206, revision 0x100302). The issue was that GPIO 3 (speaker unmute) was never initialized when using layout 32, causing internal speakers to remain physically muted even though the audio path was correctly configured. This commit adds a ConfigData entry for layout 32 that includes: - Pin configurations extracted from hardware codec dump - AFGLowPowerState (D3) for proper power management - WakeConfigData with GPIO 2+3 initialization verbs - WakeVerbReinit to preserve GPIO state across sleep/wake cycles Tested on iMac12,2 with layout 32 auto-detection via DeviceProperties. Result: - Internal speakers fully functional with DSP processing - Headphone jack with automatic switching - Internal microphone with noise reduction - Proper sleep/wake behavior 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
