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

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

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

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

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

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.

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

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

sudo alsactl store

, does that help a subsequent cold boot?

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

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

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

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.

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

Apologies for the late reply. I connect my GPU only to a DP monitor, and yes, it's directly connected to the videocard. I've disabled onboard GPU in the UEFI too

A few weird lines in journal

Is your videocard a special type or have you overclocked it in firmware ?

Is amdgpu in the modules= line in mkinitcpio.conf ?

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

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

But that's exclusive to the DP audio?
Is it strict DP or is there some adapter (eg. to HDMI) involved?
Does the journal in #7 reflect a good or a bad boot?
When the audio doesn't work, what's the output of "xrandr -q" and "glxinfo -B" (it's fine despite wayland, we want to know whether you're maybe running on the simpledrm device)
What happens when you
a) re-plug the monitor?
b) restart the GUI session?
Is this also a problem w/ any X11 session (openbox will do) - basically "does this happen because SDDM is running on X11 and the output handoff fails)

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

My apologies. I had acquired the logs from a hot boot rather than where the issue exists (cold boot). New logs at https://paste.c-net.org/EightsCrater

I don't really think my video card is a "special type". It's a Sapphire Pure RX 9070, so I suppose consumer-grade. I have indeed undervolted it and reduced it's power util cap but the issue existed well before I did this.

Yes, I do have both amdgpu and radeon in my mkinitcpio:

MODULES=(amdgpu radeon)

Sadly, adding these didn't make any difference. I keep them in my mkinitcpio anyway.

It happened with both HDMI and DP.

The DP I use is just one cable, so I'm presuming it's strict DP.

I'm a bit used to doing a restart immediately after bootup, so I'm afraid I accidentally sent logs from a working session. I will be sending fresh logs: one from a non working session (attached above) and another where it does work.

Xrandr output seems normal:

WARNING: running xrandr against an Xwayland server. See the xrandr man page for details.

I'll let you know about replugging the monitor soon. Restarting the GUI session doesn't really work, sadly. I've tried to log in through multiple DEs/WMs and even multiple greeters (SDDM and lightdm, even restarted)

I haven't tried X11 but I did try live-booting Mint on a cold boot and that failed too, so I'd presume it's happening with X11 too. I will confirm this soon.

Here's the (hot) boot right after: https://paste.c-net.org/AnywayErica

Isn't there on the cold boot, as a matter of fact, 0000:03:00.1 doesn't show up at all.

tried rescanning the PCIe bus

How and what's the output of "lspci -nn"  before and after?
Are resizable bars enabled?

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

So replugging the monitor (on a cold boot) wasn't helpful either. I guess it makes sense as you pointed out that the "enabling device" and "bound" lines aren't present for the journalctl logs for that sort of boot.

Here's the lspci -nn logs for a cold boot:

It's interesting that here we have the Navi controllers booting up. Seems like something got initialized in this case but that doesn't happen for the cold boot case.

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

Yes, the missing 03:00.1 device (as in "the OS doesn't see it at all) is clear to be the main issue since #12

what's the output of "lspci -nn"  before and after [rescanning the PCIe bus]

(What could happen is that the device appears on the bus but the sound daemon doesn't pick up/adjust on that, so you don't get audible impact from that)

If it's not rebar and unrelated to the rescan impact, does it help to artificially delay a cold boot (by waiting a bit in the bootloader)?

Thanks for clarifying. Here are the logs on a cold boot (to summarize, they're the same):

About the other mentioned possibility, I'm not sure about what gets scoped under "waiting in the bootloader". Assuming it's a hardware-side delay, I guess it should get enough time while GRUB counts down from 10s. On a hot-boot, however, I could spam the enter key to get to loading the OS asap and the audio would work. Is there any other phase (perhaps just after crossing through GRUB and into loading the OS) where you want me to introduce a delay?

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

Is there any other phase … where you want me to introduce a delay?

It would have only been to increase the time between the system receiving power and the bus being scanned - but w/ the failing rescan that's gotten unlikely anyway sad

Can you delay how long the firmware waits before loading the default EFI (ie. the time you have to enter the UEFI)?
Are there UEFI updates available for the system?
