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 <Intel Kaby Lake (HDMI/DP 8ch)> I can reliably trigger this by putting the display connected to this DP output into DPMS suspend. This HDA message appears when the display comes out of DPMS suspend. I don't use the DP audio output so cannot comment about whether the audio output keeps working or not. -- You are receiving this mail because: You are the assignee for the bug.home | help
