Sửa lỗi Lenovo Legion 5 loa bị rè tiếng (Windows 10)

Tham khảo và đã sửa thành công: 

Mục tiêu: set "High Definition Audio Controller (Microsoft)" sang chế độ MSI mode.

 

In the registry in the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI""YOUR HD AUDIO PARENT""\DeviceParameters\Interrupt Management\MessageSignaled\InterruptProperties\ "MSISupported" Change to "0x00000001"

YOUR HD AUDIO PARENT see in Device Manager>Sound, Video and game controllers\hdaudio, realtek and other\Properties\Details\Parent

 

Để tìm, chạy cmd:

 

reg query HKLM\SYSTEM\CurrentControlSet\Enum\PCI\ /s /f hdaudbus

 

That command found this registry path in my machine (and obviously this will be different than other machines): HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_1022&DEV_780D&SUBSYS_76621849&REV_01\3&11583659&0&A2 In device manager, Sound, Video and game controllers, Realtek High Definition Audio, properties, details tab, under the drop-down menu Property, I chose Parent, and I have that same string: PCI\VEN_1022&DEV_780D&SUBSYS_76621849&REV_01\3&11583659&0&A2

Therefore in my case I had to use these other commands: 

 

reg query "HKLM\SYSTEM\CurrentControlSet\Enum\PCI\VEN_1022&DEV_780D&SUBSYS_76621849&REV_01\3&11583659&0&A2\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties"
 

reg add "HKLM\SYSTEM\CurrentControlSet\Enum\PCI\VEN_1022&DEV_780D&SUBSYS_76621849&REV_01\3&11583659&0&A2\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties" /v MSISupported /t REG_DWORD /d 1 /f 

 

The first one just checks if the value exists and how it is currently set.
The second one sets the value to 1.
