From 1885ff13d4c42910b37a0e3f7c2f182520f4eed1 Mon Sep 17 00:00:00 2001 From: Callum Osmotherly callum.osmotherly@gmail.com Date: Thu, 15 Sep 2022 22:36:08 +0930 Subject: [PATCH] ALSA: hda/realtek: Enable 4-speaker output Dell Precision 5530 laptop

Just as with the 5570 (and the other Dell laptops), this enables the two subwoofer speakers on the Dell Precision 5530 together with the main ones, significantly increasing the audio quality. I've tested this myself on a 5530 and can confirm it's working as expected.
