From 90af3209742db61a7f9d7d054a16165818cfc6d8 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Tue, 30 Jun 2026 09:11:32 +0100 Subject: [PATCH] soundwire: dmi-quirks: Disable ghost Realtek on Asus Expertbook The Asus Expertbook B9406CAA also has a Realtek device in the ACPI that doesn't exist in the physical hardware. This confuses the machine driver into attempting to create DAI links for the device. Add a quirk to remove this device.
