Onboard sound not detected on Gigabyte B450

I am using a custom built mini PC around a Gigabyte B450 Aorus Pro Wi-Fi.
I am running Fedora since day 1 and am the happiest pinguin in the pool.
Sound has always been working using a bluetooth/ monitor loudspeaker
combination. Lately i decided i needed a headset, and bought a simple
Sennheiser headset.
Instead of going for Bluetooth or USB i opted for a regular 3.5 audio jack,
green for the speaker and pink for the mic. Can’t get any simpler than that, at
least that’s what i thought.
Yes, onboard sound usually sucks, but the B450 sports a Realtek ALC1220 which is
not too bad from what i’ve heard.

No sound at all. I cannot even select the onboard sound as it does not show up,
neither in alsamixer nor in pavucontrol, let alone in Gnome’s ‘sound’ settings.

If i disable the onboard HD audio in BIOS, lspci lists the HDMI audio:

0a:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Raven/Raven2/Fenghuang HDMI/DP Audio Controller [1002:15de]
Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Raven/Raven2/Fenghuang HDMI/DP Audio Controller [1002:15de]
Flags: bus master, fast devsel, latency 0, IRQ 10, IOMMU group 1

Enabling HD audio in BIOS shows

0a:00.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Raven/Raven2/Fenghuang HDMI/DP Audio Controller [1002:15de]
Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Raven/Raven2/Fenghuang HDMI/DP Audio Controller [1002:15de]
Flags: bus master, fast devsel, latency 0, IRQ 10, IOMMU group 1

0a:00.6 Audio device [0403]: Advanced Micro Devices, Inc. [AMD] Family 17h/19h HD Audio Controller [1022:15e3]
Subsystem: Gigabyte Technology Co., Ltd Device [1458:a0c3]

Looks as if the sound system is at least recognized on a hardware level.

I upgraded Fedora from 35 to 36 to no avail.
I double checked the ‘most common fedora upgrade problems’ to get rid of the
duplicate pulseaudio/ pipewire/ pulseaudio over pipewire/ … issues i had.
I tried some module options that were reported as succesful in similar cases, sich as ‘index=1.0’ or ‘model=dual-codecs’.

Any hints greatly appreciated. The output of alsa-info.sh:

Welcome to ask.fedora @dejot

Try to create a new user and check if sound works this way. Could be that you still have some configuration in your user config who changed and is different than the default F36 uses.

Please check this thread and see if the same solution works.

Nice one, i’m gonna put this into my toolbox. Should have thought of this myself.

Upgraded to latest stable, loads of new pipewire/ pulseaudio packages. Created a new user, obvious username jack. Jack could not even run alsamixer, strace report:

write(2, "cannot open mixer: No such file "...) = 45

Obviously the custom configuration in /etc/asound.conf i found somewhere did not work.

pcm.!default {
	type asym
	playback.pcm "htmi:CARD=HDMI,DEV=0"
	capture.pcm "plus:rnnoise"
}

ctl.!default {
	type hw
	card 1
}

Same problem for my user. After i removed the custom configuration in /etc/asound.conf, alsamixer comes up for me, but not for jack:

write(2, "cannot open mixer: Host is down\n") = 32

Not sure which host is down, probably bad wording. Surely one of pipewire, pulseaudio, pipewire over pulseaudio, pulseaudio over jack over alsa. And if jack in his terminal can have audio from my Gnome session.

Please do not forget @grumpey 's suggestion. Fix false ownership sounds good for me :wink:

Do not forget, if you check one of this services you should do it as --user not as sudo. In the end you want to know it for the user and not for an su/sudo user.

Holy cow! You are great! Onboard sound is detected, visible in alsamixer, and selectable from the Gnome dropdown. I can see that LINE and MIC are operational. Still cannot hear anything when switching in Gnome but i am sure this is due to a user misconfiguration somewhere.

Should i mark this thread as [Solved]? This is my first visit on askfedora.

And more importantly, how and where can i donate 20 bucks for the friendly people that fixed my audio problem? Mr. Gunthorpe and Mr. Roedel seem to be in a contract.
