Hi, I use an external monitor via HDMI with sound. hdacc1: <Intel Skylake HDA CODEC> at cad 2 on hdac0 hdaa1: <Intel Skylake Audio Function Group> at nid 1 on hdacc1 That works. Until the monitor goes into power saving mode. Then I get the following error twice: hdacc1: Unexpected unsolicited response with tag 63: ffffffff hdacc1: Unexpected unsolicited response with tag 63: ffffffff After this error sound is gone. pavucontrol still shows the sound but it is dead. I can reproduce the killing by entering xset dpms force standby on the console. Does anybody have any hints how to fix this? As a workaround is there a command I can use to manually reset hdacc1? At the moment I shutdown -r to fix this or use xset -dpms to avoid it. I am on 12.0-ALPHA1 #7 r337688 amd64 with drm-next-kmod. --=20 Liebe Gr=C3=BC=C3=9Fe Markus Graf
