      This device is on a HDA bus (personally have not reviewed it). Likely a special device driver will be required to access this device.

      See attached. Confirm that the HDA interface pins are reaching the Intel chipset.

        I've had similar issues on other ASUS laptops, and it's usually the bare copper link pads they use. They have no mask so are very susceptible to corrosion. So examine the board closely and check for any that are off in colour. Scrape with an exacto knife as often the copper is gone altogether. Bridge or jumper as necessary.

        The one I did most recently had an open circuit data line back to the CPU from the ALC chip via one of these corroded test pads.

                Maybe dry pb-free solder or whiskers over time ? Apply flux and reflow this audio IC.

                Consider to replace the part (Aliexpress ?).

                  It is replaced!

                  Suspected PCH because ACZ_SDOUT_AUD_X1 is somewhat shorted
