From ec8f26092e525ee3cb1a56d455109fd40bfff3ef Mon Sep 17 00:00:00 2001 From: Donald Menig Date: Sun, 14 Sep 2025 09:43:33 +0200 Subject: [PATCH] ALSA: hda/realtek: Add ALC295 Dell TAS2781 I2C fixup This patch adds a new fixup for the ALC295 codec on some Dell laptops that use the TAS2781 I2C amplifier. The fixup correctly initializes the amplifier and pins, allowing sound to work on all speakers of these devices. The fixup chain is added to the relevant quirk entries for Dell Polaris models.
