Hi,
Do you mean the issue is caused by the patches 1480992519-108079-1-git-send-email-libin.yang@intel.com?
I don't know whether the issues are caused directly by the specific patches; without them, digital audio does not work at all in my setup. Using analog audio however does not have the problems mentioned in my first email.
I can't see which patches are included you mentioned in the link.
I am building my kernel from drm-tip. The relevant patches enabling DP M ST audio seem to be "ALSA: hda - add DP mst verb support" [0] as well as "ALSA: hda - add DP MST audio support" [1].
Do you know if the DP MST audio mode is used in your case?
I think it is used; at least dp/hdmi audio does not work at all without building against drm-tip. (the outputs are all stated as unplugged and unavailable in pavucontrol for example) Is there any way to know for sure?
Get it. Basically, 5.1 audio should work. What format are you using for testing the 5.1 audio?
Regards, Libin
Regards, Pascal
