资源介绍：
This will enable your analog 6 channel surround sound using AppleHDA's native multi-channel DSP support. Furthermore, all jacks work!

Under System Preferences, select Internal Speakers, and there the analog 6 channel surround sound should be.
No need to create aggregate device in Audio MIDI Setup!

Internal Speakers can be automatically switched to headphone after plugging headphone in.
Internal microphone (rear mic) can be automatically switched to Line In (front mic) after plugging front mic in.

"Use ambient noise reduction" is available when using Internal microphone (rear mic.)

Add this Method DSM under HDEF:

        {
            Name (_ADR, 0x001B0000)  // _ADR: Address
            ...skip...
            Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
            {
                Store (Package (0x0E)
                    {
                        "AAPL,slot-name", 
                        Buffer (0x09)
                        {
                            "Built-in"
                        }, 

                        "name", 
                        Buffer (0x06)
                        {
                            "audio"
                        }, 

                        "model", 
                        Buffer (0x0F)
                        {
