No sound from optical port (S/PDIF out - Realtek ALC 4080) with MSI MAG X570S Edge Max Wifi Mother Board

Support Sound
1

Description
Still fairly new to Linux so help with my problem would be greatly appreciated. I bought a new motherboard (MSI MAG X570S Edge Max Wifi) and I am having trouble getting my optical output to work in Manjaro. I confirmed the sound to work in Windows 10. Also, no sound in Linux Mint 20.

Think there might be a port routing problem in the OS. Looks like the digital output shows up in my sound settings as “Digital Output (S/PDIF) USB Audio.” Not sure if this is correct.

Kernal: 5.19.1-3

since you mentioned windows:
secure boot needs to be disabled in bios
fast boot needs to be disabled in bios - you may not have this option
fast startup needs to be disabled in windows
and check audio, if it it doesnt work:

install a different kernel - 5.19.1 - from system settings/kernel, or via command:
sudo mhwd-kernel -i linux519
reboot and select it in grub menu/advanced options;
and see if it helped; if not, install sof-firmware:
sudo pacman -S sof-firmware
reboot and check

Please post more information about audio devices recognised in ALSA

sudo alsa-info.sh --upload

X570 motherboards have an unusual onboard audio codec Realtek ALC4080 that does appear to be a USB device (Device 3: in system data)

The Realtek ALC4080 on the new Intel boards demystified and the differences to the ALC1220 | Insider | igor'sLAB
The ALC4080 is a single-chip, multi-channel USB audio codec that embeds a USB 2.0 controller with a high-performance audio codec. For USB audio, it supports a standard HID-class USB audio device designed for PC motherboards and multi-channel audio systems/devices

2 similar models of MSI motherboard have been reported to alsa-project for kernel patches recently

Thanks for quick reply. I had to disable secure boot and fast boot just to get Manjaro to load properly. I am already running 5.19.1 kernel but I tried 5.18 kernel with Linux Mint and got the same result.

Thanks for the quick reply. I’ll read through the links you posted and see what I can find out.

did you installed sof-firmware and rebooted?

I did. No luck

checked the links provided by nikgnomic, it is a known bug, and you have to wait till its fixed …

ALSA data shows onboard audio device has the same hardware ID [1462:ed53] as this bug report:

MPG X570S EDGE MAX WIFI compatibility · Issue #172 · alsa-project/alsa-ucm-conf · GitHub

31:00.4 Audio device [0403]: Advanced Micro Devices, Inc. [AMD] Starship/Matisse HD Audio Controller [1022:1487]
	Subsystem: Micro-Star International Co., Ltd. [MSI] Starship/Matisse HD Audio Controller [1462:ed53]

But the Motherboard on the other system has a later Firmware Version: 1.31

I suggest you update motherboard BIOS to latest version available from manufacturer
Firmware update might include better support for onboard audio

@brahma
please see this post explaining why sof-firmware is not needed for AMD desktop systems

In my setup I had to enable spdif in the asus bios first.

Thanks for the feedback. I have updated my bios to the newest recommended on MSI’s website (version 7D53v13). I did also install a sound card firmware update from MSI.

I did not find an option for enable spdif in my bios settings. I tried to disable HD sound but that just made the on board sound unrecognizable to my OS.

Still no resolution. Might need to wait till this issue gets resolved: MPG X570S EDGE MAX WIFI compatibility · Issue #172 · alsa-project/alsa-ucm-conf · GitHub.

this comment from the issue report suggests a possible workaround

when aplay and arecord dettect this interfaces:

I try change manualy in the /etc/pulse/default.pa and works but not by default in applications

Please post more information about ALSA playback devices

aplay -l

and this to show PulseAudio modules

pactl list modules short

Looks like someone fixed this issue. At MPG X570S EDGE MAX WIFI compatibility · Issue #172 · alsa-project/alsa-ucm-conf · GitHub, perexg posted a fix. I went into my USB-Audio.conf file and made the same changes and I was able to get audio from the Optical output.
