Subject: Asus ROG STRIX X870E-E Gaming Wifi (ACL4082) - No audio from rear microphone
Date: Tue, 10 Mar 2026 17:11:16 +0100 (CET) [thread overview]

alsa-project/alsa-ucm-conf issue #718 was edited from cristian-tamblay:
The Rear Microphone is detected as Line In when I plug in my mic. There is no sound from the microphone.
Motherboard: Asus ROG STRIX X870E-E GAMING WIFI
Audio Device: ALC4082
USB ID: 0b05:1b9b
Distro: Ubuntu 24.04
Window Manager: Gnome-Shell
Before patching UCM locally, Linux exposed only generic USB audio profiles and the rear jack behaved like line input.
After adding USB ID `0b05:1b9b` to the UCM matching rules, the device now loads proper `HiFi` profiles and exposes `Microphone`, `Front Microphone`, and `Line Input` sources, but the rear microphone still does not record actual voice audio.
Recording now produces at most a small click/pop when capture starts, but no usable microphone signal.
I added `1b9b` in two places.
1) `/usr/share/alsa/ucm2/USB-Audio/USB-Audio.conf`
2) `/usr/share/alsa/ucm2/USB-Audio/Realtek/ALC4080-HiFi.conf`
`lsusb | grep -i audio`
`Bus 003 Device 004: ID 0b05:1b9b ASUSTek Computer, Inc. USB Audio`
`alsactl monitor` (unplugging and plugging mic)
```
