I have been able to work around this issue using the blacklist fix proposed in https://discuss.cachyos.org/t/asus-rog-strix-scar-16-2025-woofer-speakers-stop-working-after-6-19-update/23704 (running command echo "blacklist snd_hda_scodec_tas2781_i2c" | sudo tee /etc/modprobe.d/blacklist-tas2781.conf).

Based on my investigation & troubleshooting, the proper fix needed is adding SND_PCI_QUIRK(0x1043, 0x3f20, ...) mapping to ALC287_FIXUP_TAS2781_I2C in alc269.c.

There's the ALC287_FIXUP_TXNW2781_I2C quirk, I think these devices might need that instead.

https://share.cachyos.org/x86_64_v3/asus/ Can you try this kernel?

Seeing as you're on Nobara, you can extract the package and put snd-hda-codec-alc269.ko.zst in the correct directory (replacing the existing one).
