No Micrphone detected on ALC4080 - Gigabyte B850I Aorus Pro (rev 1.0)

Open chanster opened this issue 9 months ago • 8 comments

The Rear Microphone is not detected when I plug in my mic. I don't use the Front Audio connection as my case doesn't have I/O for it, I just used the 2 audio ports in the rear.

When I try recording directly I can get the mic to work, but it does not show up in the sound settings.

I have the same problem with this motherboard. I do use the front panel though, and an additional symptom beyond the mic (front and back) not working is that when headphones get plugged into the front port, the system recognizes that they have been plugged in, but audio continues to only play out the line out on from the back.

The issue appears similar to this one:

https://github.com/alsa-project/alsa-ucm-conf/issues/394

theksepyro avatar Mar 20 '25 13:03 theksepyro

so I have a work around for Fedora. I'm sure this can work for other distros with the correct packages. I only tested the rear audio mic also.

  1. Remove the alsa-ucm packages 
    sudo dnf remove alsa-utils alsa-ucm alsa-ucm-utils -y
  2. Install PAVU Control and Easy Effects 
    sudo dnf install pavucontrol easyeffects
  3. Restart audio services 
    systemctl --user restart pipewire pipewire-pulse wireplumber
  4. Open pavucontrol and set USB Audio to "Pro Audio"
  5. Open easyefects, under Inputs add the "Loudness" plugin and increase the Input dB until the input sounds good to you. I used Discord Mic settings to test the results.

Would be nice to have it work without this config. Not sure if this would still be a UCM issue or not, I don't play with Linux audio settings enough to understand how alsa, pulseaudio, and pipewire all work together.

chanster avatar Mar 21 '25 21:03 chanster

Only alsa-ucm package removal should be sufficient. I'll look to this issue when I find more time.

perexg avatar Mar 22 '25 15:03 perexg

Could you try changes in PR #535 ? You can replace the file (download the raw file) in /usr/share/ucm2/USB-Audio/Realtek/ALC4080-HiFi.conf or edit this file and add this change.

perexg avatar Mar 26 '25 14:03 perexg

I am grateful for you looking into this. That said, it did not solve the rear (nor front although it only appears to be addressing the rear) mic issue for me.

Edit: I should have clarified that unlike the original author of this issue, I am using Pop!_OS 22.04, but I imagine that shouldn't change much.

Edit 2: I think that this verison of Pop!_OS does not ship the latest alsa config and that I probably will have to just wait until the next pop version releases, then address it.

theksepyro avatar Mar 26 '25 21:03 theksepyro

This did work for me, Thank you! I am now seeing the rear microphone as an option in PAVU Control and Gnome Sound settings when set to the Hi-Fi 2.0 channels profile. Rear mic is still very soft to the point I was yelling into arecord just to have it pick up my voice. alsamixer shows Mic 1 at 100% (front is Mic). I have use Easy Effects to enhance using the 'Speech Processor' plugin effect. I'm not sure if this is something that can be adjusted with UCM or something else.

chanster avatar Mar 27 '25 03:03 chanster

Yeah this fix works on the X870i aorus pro motherboard as well
