From ef248d9bd616b04df8be25539a4dc5db4b6c56f4 Mon Sep 17 00:00:00 2001 From: Matt Kramer Date: Tue, 22 Mar 2022 13:48:17 -0700 Subject: ALSA: hda/realtek: Add alc256-samsung-headphone fixup This fixes the near-silence of the headphone jack on the ALC256-based Samsung Galaxy Book Flex Alpha (NP730QCJ). The magic verbs were found through trial and error, using known ALC298 hacks as inspiration. The fixup is auto-enabled only when the NP730QCJ is detected. It can be manually enabled using model=alc256-samsung-headphone.
