Public bug reported:

Hello,
I am experiencing a complete loss of audio on my new ASUS 天选 2026 (Model: 
FA401E). Both the internal speakers and the microphone are not recognized.

Symptoms:
In System Settings -> Sound, the only available output device is "Dummy Output".
No input devices are listed for the microphone.
This issue occurs on a fresh installation of Ubuntu [Your Ubuntu Version, e.g., 
24.04 LTS].

Hardware Specs:
Laptop: ASUS FA401E (2026 Model)
CPU: AMD RYZEN AI MAX+ 392 w/ Radeon™ 8060S × 24
Audio: Likely Realtek/ALSA based, but not detected.

I have checked alsamixer and only the "Pipewire" or "Dummy" card shows
up. I suspect it might be a missing firmware (SOF) or a kernel
compatibility issue with this new hardware.
