From 6d49beec658f61801e79019fd73691b17252dee3 Mon Sep 17 00:00:00 2001 From: Ian Luites Date: Mon, 31 Aug 2026 08:25:47 +0000 Subject: [PATCH] soundwire: dmi-quirks: Disable ghost Realtek on Asus GX651AX The Asus ROG Zephyrus Duo GX651AX exposes a Realtek RT722 device in ACPI which does not exist in the physical hardware. The device remains unattached while the CS42L43 and both CS35L56 devices attach successfully. This confuses the function topology machine driver into creating duplicate DAI links named SDW3-Playback-SimpleJack, and the sof_sdw probe fails with error -12. Add a model-specific quirk to remove the ghost RT722 device.
