Internal Microphone Not Working on Lenovo Yoga Slim 7 Pro with Linux Mint 22.1

Internal Microphone Not Working on Lenovo Yoga Slim 7 Pro with Linux Mint 22.1

[GitHub issues - opened]

alsa-project/alsa-ucm-conf issue #560 was opened from apirkelam:

I am a passionate and grateful new user of Linux Mint. I recently switched from Windows and have been enjoying the system stability and user-friendly experience. As a newcomer to Linux, I manage to handle many tasks with the help of the terminal and ChatGPT.

However, I am facing a persistent issue that has significantly affected my workflow:

My internal microphone is not working on my Lenovo Yoga Slim 7 Pro (AMD Ryzen 5 6600HS + Realtek ALC257 codec).

I have tested multiple approaches, including:

Switching between PulseAudio and PipeWire

Modifying /etc/modprobe.d/alsa-base.conf with various model parameters:

model=lenovo

model=ideapad

model=dual-codecs

model=auto

Verifying with alsamixer that Mic ACP LED remains off (disabled)

Using pavucontrol, but the input device shows as "Microphone (unplugged)"

The microphone works perfectly under Windows.

Due to this limitation, I am forced to carry and use an external USB microphone during my online meetings. While this workaround helps, it’s inconvenient, and I hope this issue can be resolved at the driver/firmware/kernel level for AMD + Realtek-based laptops like mine.

Note: Not long ago, I was able to use this same internal microphone under Linux Mint on this very laptop, including in Zoom-like applications. This suggests that either a kernel, driver, or PipeWire update might have broken support recently.

System Details:

Distro: Linux Mint 22.1 Xia (based on Ubuntu 24.04 Noble)

Kernel: 6.8.0-59-generic

Desktop: Cinnamon 6.4.8 (Muffin 6.4.1)

Laptop: Lenovo Yoga Slim 7 Pro 14ARH7

CPU: AMD Ryzen 5 6600HS Creator Edition

Audio Codec: Realtek ALC257 (with ACP/ACP6x support)

Sound backends tested: PulseAudio, PipeWire

Audio devices detected:

AMD Rembrandt HD Audio (snd_hda_intel)

AMD ACP/ACP6x Audio Coprocessor (snd_pci_acp6x)

AMD Family 17h/19h HD Audio (snd_hda_intel)

Current workaround: BOYA M1 via USB-C DAC (recognized as USB Audio)

Please consider improving support for this hardware combination. I really love Linux Mint and want to stick with it long-term.

Thank you for your work!

Best regards,

Dear Linux Mint Support Team,

many tasks with the help of the terminal and ChatGPT.

However, I am facing a persistent issue that has significantly affected
