    Subject[PATCH 5.10 047/141] ALSA: hda/realtek: Enable 4-speaker output Dell Precision 5530 laptop
    Date
    From: Callum Osmotherly <callum.osmotherly@gmail.com>

    commit 1885ff13d4c42910b37a0e3f7c2f182520f4eed1 upstream.

    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.
