https://bugzilla.kernel.org/show_bug.cgi?id=199493 Bug ID: 199493 Summary: no audio over HDMI with amdgpu.dc=1 (on R9 380X) Product: Drivers Version: 2.5 Kernel Version: 4.17.0-rc2 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: haro41@xxxxxx Regression: No Audio over HDMI doesn't work (no sound), if dc is enabled (amdgpu.dc=1). Hardware is R9 380X (Tonga), i use ALSA only. With dc disabled (amdgpu.dc=0), audio basically works, but i get 'noisy' sound usually. The only way to get correct audio over HDMI is currently: disable dc (amdgpu.dc=0) and start windows once, then warm boot to linux. It looks like: the windows driver is initializing the hardware correctly, while amdgpu doesn't. -- 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
