GTX 1070 Foundation DP audio work，but the volume can not be adjusted

[zysuper]

1. I use audio_cloverHDMI-120.command, and after running, automatically download the SSDT-HDMI-NVIDIA-PEG0.aml.
2. After restarting the system, then found that the sound card settings out more "DISPLAYPORT". But can not find "output controls".
3. see below pic:
4. Now I play the video with a sound, but I can not control the volume size!

5.Accessories are clover config.plist, audio_cloverHDMI-120.command output file, and use ssdt file。
6.more problem report information added.( "dpci-manager status" and "ioreg"). All this file packaged in problem-report-file.zip.

Got it. I used the soundflower + soundflowerbed to solve the problem of poor volume adjustment. Thanks for @toleda.

Could you write here a short tutorial how you did it? I have exact the same problem with my 1070: working audio without volume ctrl.
