The subwoofer isn't enabled out-of-the-box. It seems like this is a similar issue as previous dell models.
I've looked at a possible patch and tried (to no avail) to create a patch and test it out locally. Never build the kernel before.
But I've looked at previous entries, used lspci -vmnn to discover the right Svendor and SDevice.
So I believe this will fix the issue in sound/pci/hda/patch_realtek.c
SND_PCI_QUIRK(0x1028, 0x0b19, "Dell XPS 15 9520", ALC289_FIXUP_DUAL_SPK)
Happy to test out any builds etc.

Patch to fix sound quirk
I have successfully compiled the kernel (version 5.17.11) and confirmed the sound working properly.
Filled in patch, this has been applied see: https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/?id=15dad62f4bdb5dc0f0efde8181d680db9963544c
Hello, is there any chance of getting this backported to the 5.15.x series?
5.17.x has just been made EOL and 5.18.x is probably a little too bleeding edge for the most. For example, Ubuntu 22.04 LTS will be coming out with 5.15.x.
