No Audio From Front-Panel ALC4080 MSI MPG Z790I EDGE WIFI

Edit: This motherboard has a red connector on the back which also works as
audio output. I am having no problems with that, so if you are having trouble,
try using that port. The issue is about the front-panel connector having no
output by default. This probably requires some alsa configuration.

Hi.

When I first boot, front-panel audio does not work until I run

pacmd load-module module-alsa-sink device=hw:Audio,1 control='PCM',1

to make the audio work (if I am using PulseAudio).

How can I have this done automatically, and how do I do this if I am using
PipeWire?

Output of lsusb:

$ lsusb

Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

And it is in

$ grep '0db0:62a4' /usr/share/alsa/ucm2/USB-Audio/USB-Audio.conf
                # 0db0:62a4 MSI MPG Z790I Edge WiFi

under "If.realtek-alc4080", so I guess that looks correct.

Finally, some lspci output

What do I need to do to get this to work automatically or at least what is the
equivalent command for PipeWire?

Thanks.

Do you have alsa-utils installed? After installation of alsa-utils, by default, it should keep track of settings at /var/lib/alsa/asound.state.

Thanks for the reply.

Yes I do have alsa-utils installed:

$ pacman -Qe | grep alsa
alsa-utils 1.2.11-1
pulseaudio-alsa 1:1.2.7.1-2
$ systemctl list-units | grep alsa
  alsa-restore.service                                                                                    loaded active exited    Save/Restore Sound Card State

Re: No Audio From Front-Panel ALC4080 MSI MPG Z790I EDGE WIFI

You can read this to migrate to Pipewire from Pulseaudio:
https://gitlab.freedesktop.org/pipewire … #modules-1

Pipewire (and pipewire-pulse) does not have pacmd, but you can still use "pactl" to load the module. I understand you are using this hack because the sink is not automatically being created by pulseaudio for some reason. I also have ALC4080 but on an MSI X650 Tomahawk Wifi motherboard, but the sink profile is created properly on mine after the recent alsa-ucm-conf update. I am using pipewire by the way. To configure on pipewire, you would use wpctl or pw-cli (more difficult to use).

Can you show output of "alsaucm listcards"?

Re: No Audio From Front-Panel ALC4080 MSI MPG Z790I EDGE WIFI

$ alsaucm listcards
  0: hw:1
    Generic USB Audio at usb-0000:00:14.0-9, high speed

On PulseAudio, I originally only have "USB Audio Analog Stereo", then, running

pactl load-module module-alsa-sink device=hw:Audio,1 control='PCM',1

I get just "USB Audio"  which has working audio output (in addition to the "USB
Audio Analog Stereo").

After installing PipeWire, I originally only have "USB Audio Analog Stereo"
which does not work. After running the same command as above, I get "ALSA Sink
on hw:Audio,1" which works (after fiddling around with alsamixer).

Thank you. I can at least use PipeWire now.. But I just realized I do not know
if the audio input works with this hack. I don't need it right now and I do not
have any device that I can use as a mic through that audio jack, so oh well...

I'm still open to trying things to properly fix this issue and have it all work
automagically.

Re: No Audio From Front-Panel ALC4080 MSI MPG Z790I EDGE WIFI

I just found out there is a audio connector on the motherboard itself.. It has
a red color (rather than the standard green) so I just ignored it initially.

Anyway, the default "USB Audio" is outputting from there without any other
changes.

For the front-panel, I need to load the PCM thing and unmute it in alsamixer.

So if I ever feel motivated enough, I guess I need to do some alsa
configuration to map devices or something...

Looks like it may be a "high power" output that has more drive capability than does a standard line out.

Re: No Audio From Front-Panel ALC4080 MSI MPG Z790I EDGE WIFI

Thanks for the info.

The reason I did not mark this as solved is because the original issue is about
front-panel audio. I will eventually get to that (hopefully). But I am not that
motivated currently because I don't really use this as a desktop so I don't
care about the audio... But I will someday get to it and make a post addressing
that issue here when I do.

I guess I will update the original post to make this more clear.

Nope, it was me not reading the first post again.
