How to Fix OpenCore 1.0.0 Realtek ALC3820-CG No Sound Output on macOS
Wi-Fi, Bluetooth, AWDL, Continuity and Location Services problems usually come from chipset support, kext pairing, privacy settings or network-location corruption. On Hackintosh systems, Location Services and Continuity depend on working Wi-Fi, Bluetooth, AWDL and correct AirportItlwm or itlwm/HeliPort behaviour.
Quick Checks
- Backup current state: Save a copy of your working EFI and run a full system backup before changing settings.
- Identify hardware components: Note down your exact CPU, GPU, Wi-Fi card, and motherboard/laptop model.
- Ensure utility alignment: Keep OpenCore, OCLP, and ProperTree updated.
Fix Steps
- Create a rollback point: Make a Time Machine backup and keep a copy of your last working EFI folder before editing OpenCore, kexts or root patches.
- Confirm the exact chipset: Identify the Wi-Fi, Bluetooth and Ethernet controller from System Information, Hackintool or Linux/Windows device manager.
- Use the correct network stack: Match AirportItlwm, itlwm, HeliPort, IntelBluetoothFirmware and BlueToolFixup to the exact macOS version.
- Reset macOS network state: Remove the current Wi-Fi service, reboot, add it again, then reconnect to a simple WPA2 network before testing advanced features.
- Check privacy permissions: Open System Settings and confirm Location Services, Maps, Weather and system services are enabled.
- Test Apple features separately: Verify normal internet first, then Bluetooth, then AirDrop/Continuity. Do not debug all three at the same time.
Do Not Continue If
- Do not continue if: you do not have a working EFI backup, a Time Machine backup, or another bootable macOS installer.
- Stop and capture evidence: if the machine stops booting, take a photo of the last verbose line before changing more settings.
Verify It Worked
- Maps can locate you without falling back to a stale location.
- Wi-Fi reconnects after reboot and sleep.
- Bluetooth remains available after a cold boot.
- Console no longer shows repeated wireless or location daemon errors.
Rollback
- Restore the previous EFI if Wi-Fi disappears completely.
- Switch from AirportItlwm to itlwm + HeliPort, or the reverse, if the issue is specific to one driver path.
- Use Ethernet or USB tethering while testing so you do not lose access to downloads.
Next Action
- Test now: reboot twice, reproduce the original problem, and confirm whether the same symptom returns.
- If it still fails: record the Mac model, macOS build, OpenCore or OCLP version, GPU, Wi-Fi/Bluetooth chipset, and the last visible error.
- Read next: use the related searches below for the nearest OpenCore or OCLP fix before making another change.

Original Question: "OpenCore 1.0.0 Realtek ALC3820-CG No Sound Output"
 | I create USB bootable drive and successfully install Sonoma on hard drive. However, there isn't any installed sound chip on MacOS. My Dell PC specification is listed as below. Dell Inspiron 3670 Motherboard B360 Intel i5-8500 cpu Display UHD630 chipset Sound Realtek ALC3820-CG USB 3.1 (Front) x 2 USB 2.0 (Back) x 4 HDMI & VGA M.2 2230 x 1 M.2 2280 x 1 Wifi Intel AX200 I have added "AppleALC.kext" and applied on opencore 1.0.0. However, the sound chip cannot detected on MacOS Sonoma. May anyone give me hint how to activate the sound chip on MacOS? Another question: I am a newbie to Hackintosh. I have installed macOS on my hard drive. How can I modify the kext, ACPI, or boot configuration on the hard drive? I believe all these files have been copied from the USB to the hard drive. How can I modify them on the hard drive? Thanks in advanced. [link] [comments] |
