No sound from internal speakers using Linux

[Gttmhl]

Hi all,

I managed to make the speakers work by applying this patch: https://lore.kernel.org/lkml/20220811053950.11810-1-[Personal Information removed]/ to the 6.2rc5 version of the Manjaro kernel.

Just for sharing: 

1. Pulled code from manjaro repository: https://gitlab.manjaro.org/packages/core/linux62.git/
2. Applyed the two edits on the to specified files
3. Packed the kernel: makepkg --noextract --clean --cleanbuild
4. Installed the two zst packages: sudo pacman -U linux62-headers-6.2.0rc5-1-x86_64.pkg.tar.zst linux62-6.2.0rc5-1-x86_64.pkg.tar.zst

🙂

Cheers,

Michael

@Waldfee Have you made any progress on getting sound working? I also have a 15-ew0000 running Linux (mint at the moment) and would love to get some sound working.

Hi there, unfortunately I haven't hat the time yet and I will wait for Ubuntu 23.04. It is supposed to Feature kernel 6.2. The lautet is a good Basis for a fixed DKMS module.

Thank you for the quick response. The link you included was removed. Do you think this will help at all?

The approach of tweaking snd_hda_intel driver values did not work in my case. So I don't think the link is helpful.

Spoiler

I'd rather go with the patch suggested by Michael above. I would package this change into a DKMS module which has the advantage that the kernel does not have to be recompiled. So one could use the unmodified mainstream kernel from Ubuntu 23.04 once it is out together with the DKMS module. But of course I have to find out the correct patch for the 15-ew0000 model in the first place.

What is required to get the correct path? is it trial and error? The patch linked doesn't seem to do much more than call the `ALC287_FIXUP_CS35L41_I2C_2` quirk for that HP model and CSC3551 amp. 

What are the odds that using the linked path, with the correct line in patch_realtek.c would work?

`SND_PCI_QUIRK(0x103c, 0x8a29, "HP Envy x360 15-ew0xxx", LC287_FIXUP_CS35L41_I2C_2),`

Holy **bleep**, that did work!, compiled on 6.2.0-rc4 (just the source I had laying around). I have sound now!

I lost the internal mic tho...

I can't believe it, I have been looking for a fix for this issue for months - thanks so much!  As posted, the fix does not work for my model (16-h0xxx), but I found I can add a line that is for this specific model.  This is the patch I applied to linux 6.2.8 (I used arch linux aur):
