[SOLVED] PulseAudio only displays Dummy Output sink

SOLVED EDIT: Check your BIOS settings...!

Original Post:

Fresh install of Arch tonight, with Gnome 3 as the only desktop environment. My platform is an old AMD APU (A10-7860K, specifically) and an RX 480. I'm attempting to play audio through the GPU's DisplayPort.

What I gather from the following is that the onboard HDMI from the APU is detected, though the onboard analog audio output is not. The chassis' front panel audio also doesn't appear to be detected. Similarly, the HDMI and DisplayPort outputs from the GPU are detected. However, while PulseAudio does appear to have permission to hijack the various audio sources, it doesn't assign any sinks to them.

[patrick@redbox ~]$ sudo fuser -v /dev/snd/*
                     USER        PID ACCESS COMMAND

That error for "backend-ofono.c" shows up on my laptop, too, where audio works just fine.

I'm really at a loss for what else to investigate, here. Any help would be appreciated.

Re: [SOLVED] PulseAudio only displays Dummy Output sink

Kernel support for AMDs DC (which is necessary for HDMI/DP output) has only landed in 4.15,  so if you can't wait, giving the linux-mainline package from the AUR a whirl might help you out.

Re: [SOLVED] PulseAudio only displays Dummy Output sink

Hot damn, really? So when I was doing audio over DisplayPort with my Vega 64 on Debian, that was only working because of the closed source drivers? (I bought it on launch day and fought with it for a good many hours just to get 3440x1440@100hz working on this display, but audio never gave me any issues.)

Re: [SOLVED] PulseAudio only displays Dummy Output sink

Actually... Ok, so that's DP/HDMI explained, but what about the analog HD audio stuff? I'm still only showing the APU and GPU's sound cards:

[patrick@redbox amdgpu-pro-fans]$ lspci | grep -ni audio
3:00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Kaveri HDMI/DP Audio Controller

Re: [SOLVED] PulseAudio only displays Dummy Output sink

Well, derp. This mobo/CPU/RAM is an old HTPC repurposed to a desktop. That said, I had disabled the onboard audio to force the then-installed OpenELEC to provide audio over the HDMI connection. But, does that means that audio over HDMI existed in the kernel a year or two ago for Kaveri-based APU's but has only just now come around for Polaris-based GPU's? Not complaining about my free software or anything, just wondering. smile

But for all intents and purposes, I'll mark this solved. Haha.

Re: [SOLVED] PulseAudio only displays Dummy Output sink

Well yeah amdgpu is an entirely new driver stack and the necessary parts for DP/HDMI output was only upstreamed now. They made an attempt at that way earlier, but the patch was rejected due to not being up to the kernel maintainers standards. So it took a while, see here as well: https://wiki.archlinux.org/index.php/AM … Vega_cards

Also for the future, if you are the only one posting in between, please append new information to your last post rather than bumping.
