Tested on Omarchy / Arch Linux, kernel 7.0.0+ mainline (the AMD ACP70 PX13 quirks landed in mainline 2026-03-16 and ship in 7.0).
This was the first publicly-confirmed working speaker setup for this laptop — kernel side worked out of the box on 7.0, but the TAS2783 SmartAmp speaker calibration blobs (1714-1-8.bin, 1714-1-B.bin) are not yet in linux-firmware. They ship in the official ASUS Windows driver. Below is a recipe to extract your own copy and install them.
If you're hitting slave-tas2783 ... Direct firmware load for 1714-1-8.bin failed with error -2 in dmesg and wpctl status shows only Dummy Output, this is for you.
