sof_sdw probe fails with duplicate "SDW3-Playback-SimpleJack" (-EEXIST) → no sound card on ASUS UX8407AA (Panther Lake)

I notice audio devices not detected -- but the external/bluetooth audio work perfectly
I tried to probe this problem using claude here's full report and logs

thank you in advance. It worked perfectly on older linux kernel like 7.1 stable but now it is not.

Yeah apologies we have been getting a few of these, devices that have a Realtek device that doesn't exist, some changes made the kernel a little more sensitive to that.

Could you make sure your kernel has all the patches from this branch:

https://github.com/charleskeepax/linux/commits/v7.0-cs42l43/

But it looks your model is not one we knew about yet.

product_name: Zenbook Duo UX8407AA
board_name: UX8407AA

So you will need something like this as well:

0001-soundwire-dmi-quirks-Disable-ghost-Realtek-on-Asus-Z.patch

If that works for you I will get it upstreamed and added to my fixes branch there.
