When i direct connect the monitor using miniDP cable, there is no DP audio. But after i close the laptop's screen and only use external monitor, it will appear.
Update Problem Reporting Files today.

These values appear only after i close the lid. They are still existing if i reopen the lid, but when i reconnect the cable, they will disappear.

Try removing FakePCIID_Intel_HDMI_Audio.kext if you have it both in Clover and/or on the system volume. It helped me.
I forgot to include FakePCIID_Intel_HDMI_Audio.kext before...
Now it's in /L/E, but it still not work.
Actually i don't think FakePCIID_Intel_HDMI_Audio.kext is needed for this build, as for Thinkpad X240 Intel Audio is shown to be 8086:0A0C in DPCIManager, which is supported according to https://github.com/the-darkvoid/OS-X-Fake-PCI-ID

Remove WhateverGreen.kext (it might be interfering), use IntelGraphicsFixup.kext instead.

It seems to be solved.
Considering that kexts like IntelGraphicsFixup are no longer updated anymore, i should report this bug to WhateverGreen developers. But no support is provided for the time being.
