When I select HDMI-Audio output with pavucontrol (since it's not even listed in Gnome) my system will still freeze. Trying to play some audiofile with aplay -D on that device will also freeze my system (sometimes even just aplay -l will cause a freeze) I have attatched the dmesg-output after connecting the tv with hdmi my system: Kernel: 4.17.0 DE: GNOME 3.28.2 CPU: Intel Core i5-4690S GPU: AMD Radeon R9 290 -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
