Subject: [PATCH] soundwire: dmi-quirks: Disable ghost Realtek on Asus Zenbook Duo
Date: Mon, 20 Jul 2026 10:57:41 +0100 [thread overview]
Message-ID: <20260720095741.3592825-1-ckeepax@opensource.cirrus.com> (raw)
The Asus Zenbook Duo 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.
