Unfortunately I can’t use the front ports on the case because the cables for it don’t reach the plug on the motherboard.

Haven’t thought to try OBS, I’ll have to give it a go tomorrow!

I do appreciate the attempt to help me troubleshoot it, even if unsuccessful!

Yyyyep, shows up on lsusb

I went and booted into Windows to double check how the audio devices are set up and I don’t think I’ve ever seen onboard audio controllers show up like this with previous motherboards, which might explain why I’m having such a hard time getting it to work on Linux. It seems to be throwing whatever is plugged into the jack ports through two different hoops. The devices themselves (Speakers and Mac Mini) aren’t directly connecting to the integrated Realtek audio card, and it seems like there’s another layer of audio processing happening in-between. I don’t know, I know nothing about audio so I’m kinda talking out of my ass based on what I’m expecting to see and what I’m seeing…

This is what lspci -k returns, I’m seeing no mention of Realtek and the only audio related things I’m seeing appear to be the CPU’s iGPU (73:00.1) and the GPU’s (01:00.1) audio…

The deeper I dig the less I understand.

Edit: had to redact the code-block because it seems there’s a character limit and it was long enough to hit it.

The only actual microphone I have is a USB microphone, and I’ve had no problem using it for Discord calls, but that unfortunately doesn’t apply to the Line In port.

Currently looking up how to figure out if I can force Arch to use snd_hda_intel if it isn’t already.

Same as other audio software, “USB Audio Device” for both Output and Input, both are enabled and volume at 75% or higher, capture is enabled on the Input, if Kmix shows audio activity levels then it’s not detecting anything either despite media playing on the Mac Mini

If I plug the speakers directly to the Mac Mini and play media, audio comes out of the speakers. Running arecord to try to record the Mac Mini’s audio coming in from Line In results in a blank WAV file with no audio.

I believe KDE’s sound settings is supposed to show audio activity levels, but to be extra sure I tried pavucontrol and other apps (like Discord) and they all show zero audio activity levels despite Line In being enabled and volume up.

The HD-Audio Generic is the CPU’s (AMD Ryzen 7 9700X) iGPU (ATI R6xx HDMI) audio, when I select it, it shows four S/PDIF items that are disabled and cannot be enabled.

Disabling USB Audio in KDE’s sound settings and enabling HD-Audio Generic gives 8 audio channel that provide no audio whatsoever.

I’m not seeing anything about loopback mixing, but here’s how my alsamixer looks at the moment:

In KDE Plasma’s sound settings, both ports are set correctly, I tried messing around with the profiles but Analog Stereo Duplex seems to be the default and seems to work best.

All settings are pretty much identical compared to before the motherboard upgrade, back when audio loopback worked no problem.

So I’ve only got two machines:

• The Mac Mini, which has one audio jack (labelled Headphones, audio out).
• My Main PC, which had two audio jacks (Line Out/Speakers, and Line In/Mic)

The main PC is on a dual boot setup (two NVMes, one solely for Arch, the other solely for Windows).

The Mac Mini’s audio out is plugged to the Main PC’s Line In/Mic, and the Main PC’s Line Out/Speakers is plugged to the Speakers.

Both the input from the Mac Mini and the audio loopback (making the input play out on the speakers) work on Windows, neither work on Linux.

Everything seems to be enabled and unmuted on Linux.

This is gonna sound even stupider, I actually got my cables mixed up and the cable I plugged into the Mac Mini thinking it was the Speakers was actually the other end of the Line In cable so audio was being sent to nowhere.

Plugged the actual Speakers cable in the Mac Mini and audio played find through the Speakers.

Re-arranged the cables back to the previous setup and the issue remains :(

Ohhh very interesting, didn’t think to try THAT.

When I unplug the jack from the Mac Mini, the audio plays out from the Mac Mini’s internal speaker (that I tried).

But when I unplug the speakers from the main PC and plug them into the Mac Mini, nothing plays through the speakers.

Outputs listed on the Mac Mini are: LG ULTRAGEAR (HDMI), External Headphones (Headphone port), and Mac mini Speakers (Built-in).

Default audio device is set to External Headphones (the jack port i’m using that worked perfectly before), unmuted and volume set to 75%, so audio SHOULD play, but it does not.

Edit: really weird that it works fine through Windows though. Audio from the Mac Mini’s plays fine when plugged to the main PC and it’s booted to Windows, but not through Linux and not through the Speakers directly??

Oop yeah I should’ve probably specified that.

Speakers work fine, it’s specifically the Line In that doesn’t seem to work. Motherboard only has two jack ports: Line Out (Speakers, works), and Line In (doesn’t work at all).

Once every couple of days the Speakers audio will cut out for about 5s and come back, but I can live with that (couldn’t seem to find errors logged relating to this).

While having a video playing on the Mac Mini so I’d have a constant source of noise, I tried using arecord and aplay to test if any audio at all was coming in, got nothing. I tried testing the “microphone” in Discord, Discord tells me it’s not getting anything at all (but it does do a brief crackle right when I click “Let’s check” under the mic testing option).
