Audio is only supported on amdgpu with DAL: https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-4.7 Excuse my dumb question, what does "DAL" mean? And more importantly how do I get it? I use a self-compiled kernel 4.8.9 and I did not find any configuration option that looked like DAL. (In reply to Matthias Nagel from comment #2) > Excuse my dumb question, what does "DAL" mean?

It's not upstream yet, so you'd need to use that branch until it is. OK, thanks. In this case I prefer to stay with the kernel provided by my distro. Now, I know that it is not a bug but just a missing feature that is hopefully coming soon and I am willing to wait. I found some reports around that claimed that audio should be working with amdgpu since kernel 4.6 and so I thought I was missing something. |

Sound over DisplayPort with Radeon R9 380 and amdgpu does not work. The device is listed by lspci, the driver "snd_hda_intel" is loaded and the card is detected by ALSA. ALSA lists six possible devices but none of them works. No matter what device configuration I select in PulseAudio/Phonon (HDMI 0 through HDMI 5) my monitor stays silent. If I try to by-bass PulseAudio and directly try to play an audio file with aplay I get the same negative result. # lspci -v -s 01:00.1 01:00.1 Audio device: Advanced Micro Devices, Inc.
