I'm on 15.0-RELEASE-p2 GENERIC amd64 and get the following message: hdacc1: Unexpected unsolicited response with tag 63: ffffffff /dev/sndstat shows this output is I can reliably trigger this by putting the display connected to this DP out= put into DPMS suspend. This HDA message appears when the display comes out of D= PMS suspend. I don't use the DP audio output so cannot comment about whether the audio output keeps working or not. --=20 You are receiving this mail because: You are the assignee for the bug.=
