RX 9070 on a cold boot can't initialize any audio for monitor speakers

Rammerhead · 2026-06-20 09:09:53

Greetings, I have been dealing with a very annoying issue ever since I seemingly got this system for the first time (which was some months ago) but I never experienced it much before as I used a bluetooth headset. I'm running a rig of the following specs:

Ryzen 9 9900X
Giagabyte B650 AORUS ELITE AX ICE
RX 9070 (not the XT version)

The issue is simple. If I cold boot (i.e. the system isn't initially running and I start it), I'm able to log into my window manager and everything mostly works, but the audio on the monitor speakers don't work and say "Dummy Output". If I reboot the system, this gets fixed and I'm able to see "Vega XX HDMI/DP audio" or something along the same lines.

So, to summarize, a cold boot = no audio. Warm boot = yes audio.

Audio:
  Message: No device data found.
  API: ALSA v: k7.0.12-zen1-1-zen status: kernel-api
  Server-1: PipeWire v: 1.6.6 status: active

This issue does not appear for my integrated GPU, which is able to initialize audio right from a cold boot. I've tried doing the following:

On BIOS:

* disable "fast boot"
* forcefully disable integrated GPU as well as the HD audio controller (which seems to pertain only to the integrated gpu)

Inside linux (I use Niri):

* restarted pipewire and wireplumber after logging in
* tried rescanning the PCIe bus

Outside Linux:

* Funnily, the issue even appears on Linux mint if I do a cold boot, so it's not really specific to Arch.

I would like to test out any other possible software-side workarounds or solutions before I deem that it's really a hardware-side issue. Can anyone please help?

I am indeed on a newer kernel 7.0.12-zen1-1-zen and have the following mesa version:

GPU0:
	apiVersion         = 1.4.348
	driverVersion      = 26.1.2
	vendorID           = 0x1002
	deviceID           = 0x7550
	deviceType         = PHYSICAL_DEVICE_TYPE_DISCRETE_GPU
	deviceName         = AMD Radeon RX 9070 (RADV GFX1201)
	driverID           = DRIVER_ID_MESA_RADV
	driverName         = radv
	driverInfo         = Mesa 26.1.2-arch1.2

Stuff like that is can often be tied to the UEFI version, how up to date are you there?

Thanks for the suggestion. I found that my BIOS version was released about a year and a half ago. I updated my BIOS, but sadly, the issue still persists.

I was thinking I could probably instead have my Linux system detect if it's cold starting and do a hot-start immediately.

Mhm... when on a fixed boot where it works, try running an explicit

sudo alsactl store

, does that help a subsequent cold boot?

This too didn't help. Guessing it is indeed something else at the hardware side. It's a bizarre issue but not something that's blocking me from getting my things done, so it seems I might just need to continue with this, for the time being, at least. I'll definitely still appreciate any other suggestions

This sounds very much like a timing issue where something tries to access hw before its fully initialised.

Is this with a HDMI , DP or something else monitor ? Is is connected directly to the vidoecard ?
Please run (as root)

# journalctl -b | curl -s -H "Accept: application/json, */*" --upload-file - 'https://paste.c-net.org/'

and post the link it outputs.
