<pre>Hello keqiao.
I verified this issue in the same way that you ask, and I did it with this
configuration:
Platform HSD-NUC with drm-tip 4.12.0-rc7+ connected (mDP-DP) to monitor - ASUS
(1920x1080) (audio) -
Platform HSD-NUC with drm-tip 4.12.0-rc7+ connected (mHDMI-HDMI) to monitor -
ASUS (1920x1080) (audio) -
And I had the same result for both test, the audio is unavailable via DP or
HDMI
This is the general configuration.
