[alsa-devel] HBR support on DP]
Hi Takashi/All,
On skylake platforms HBR audio works fine through over HDMI1.4, but not over DP ports. Looking for information if anyone is aware of if HBR audio was ever enabled/tested over DP ports? Is there any specific setting to be done to play over DP using aplay?
Regards, Subhransu

I don't know of the difference regarding HBR setup between HDMI/DP from HD-audio POV. It's just a pin control bit.
I guess the difference is rather in i915 graphics side?

Not sure. Checking with graphics people as well.
