4 Speaker Subwoofer Dell XPS 15 [9500/9510/9520/9530]

Hello my fellow friends,

I turn to you at this dark hour for help. On my XPS 15 9500, only the tweeters work, not the subwoofers. This seems to be a known issue according to forum posts like:
https://askubuntu.com/questions/1486065 … untu-23-04

It appears to me that this can be fixed by adding a patch to the kernel:
https://github.com/rikvanderkemp/dell-xps-15-9520-audio

But by taking a look at the current kernel, those patches seem to already be added to the mainline except for my machine, XPS 15 9500:
File: sound/pci/hda/patch_realtek.c

SND_PCI_QUIRK(0x1028, 0x0a61, "Dell XPS 15 9510", ALC289_FIXUP_DUAL_SPK),

SND_PCI_QUIRK(0x1028, 0x0b19, "Dell XPS 15 9520", ALC289_FIXUP_DUAL_SPK),

It's at least not explicitly mentioned.

According to spec sheets, those successors of my machine should use the same Audio Controller:
https://www.dell.com/support/manuals/de … d941403f53
https://www.dell.com/support/manuals/de … lang=en-us

My knowledge about the kernel and C is really limited:
So I do not know how to apply a patch for my machine nor do I know how to build my own kernel.

Has anyone experienced a similar issue or does anyone have one of those successor machines and can confirm that the subwoofers work by default?

This patch only fixes sound quality for tweeters, but subwoofers won't work. To let subwoofers work it is a complicated job, as I found.
