Hi Mario, Bjorn, I'm the author of the A9WJG subsystem-ID quirk that Diogo mentioned in his commit message, so a data point from the MSI side. I hit the same problem on an MSI Raider A18 HX A9WJG (MS-182L): the ACP is rev 0x62 (1022:15e2 at 6a:00.5) with the Ryzen HD Audio controller (1022:15e3) at 6a:00.6, and HD Audio stops working after resume, same as Diogo describes. This is on the CachyOS 7.3 kernel. Regarding the BIOS question: I'm on the latest BIOS for this model, E182LAMS.31B (dated 05/26/2026), so a BIOS update isn't available as a workaround here either. That makes at least two different vendors (ASUS and MSI) with the latest firmware still affected. Given that, a generic fix keyed on the ACP revision, as in Diogo's patch, looks preferable to per-board subsystem-ID quirks. I'm happy to test any follow-up version on this machine. Thanks, David
