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?

Regards,
Pascal
