Bug ID: 208679 Summary: AMDGPU - HDMI audio not available Product: Drivers Version: 2.5 Kernel Version: 5.7.10 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: kurmikon@libero.it Regression: No
Hello, I have an HP laptop with the following specs:
0:00.0 Host bridge: Advanced Micro Devices, Inc. [AMD] Family 16h (Models 30h-3fh) Processor Root Complex 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mullins [Radeon R3 Graphics] (rev 40) 00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Kabini HDMI/DP Audio
The VGA belongs to CIK Sea Island Family. The system is running Arch Linux with latest kernel without issues. Used radeon driver for years, then switched to amdgpu to test how they work. No issues until I needed to play something through HDMI port.
Video is good, but audio device is not available. So I switched back to radeon and HDMI audio is working, but I'm experiencing gpu lockup freezes. So I need to switch back to amdgpu which is more reliable since I don't get freezes even if its support for CIK is experimental. But I don't get HDMI audio with this driver.
When I do a test with aplay, it shows the following error: "set_params:1349: Channels count non available"
Is there a way to get HDMI audio working on amdgpu for my card? Thanks.
