No sound from internal speakers using Linux

[scorpicok]

Does anybody know which quirk should be added to patch_realtek.c for laptop model 'HP ENVY Laptop 17-cr0xxx'?

[luxwarp]

Finally guys!! We are now approaching a working Linux kernel for almost all HP Envy/x360 laptops! Kernel 6.9 that soon will be release as RC1 will have a lot of fixes for the internal speakers. As you can see in this commit https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/diff/sound/pci/hda/patch_realtek....

i have already tried patching the 6.7.9 and 6.8 kernel with my specific quirk for my Hp Envy x360 13-bf000 and it works perfectly!

So if you don't have the knowledge to patch your own kernel then make sure to get the 6.9 kernel when it gets released!

The guys from the linux community and developers from Cirrus has made an awesome job, and no thanks to HP. This is why OPEN SOURCE RULES!

That's awesome news. Any chance you'd walk through it a bit? I'd like to use OpenSUSE which is on the 6.7.9 kernel now. I've got a "15-ee0xxx" Envy x360. Do the mute speakers and/or mic LED indicators work too? I see some stuff on that page about LEDs. 

[luxwarp]

Hi!.

The mute leds are not working for my model right now. And i haven't really looked in to it but there are some quirks popping up that fixes the led on some machines so it should work pretty soon.

I have an DKMS module that patches the kernel for me. I have begin to setup instructions and code on my github where you also can find the dkms module. https://github.com/luxwarp/hp-envy-x360-13-bf0xxx-linux/tree/main/hp-envy-x360-13-bf0xxx-realtek-0.1

However in the patch-file you need to update the quirk to match your subsystem id which you can find out by running

cat /sys/class/sound/hwC0D0/subsystem_id

For instance, my id is "0x103c8a28"

Okay, the I2C_2 only matters if it is actually an ALC287, check that is the right one in dmesg as that sets some LED parameters, then it is adding the right bit after for the LEDs, I've not narrowed this down to the right one yet for this 17 inch (ruled out COEFBIT so far, I'm just compiling into kernel itself), but need to check but any ALC245 quirk works (and that is the firmware being loaded in dmesg) as well as the ALC287 one in your patch there.for the sound side.

Hi, sorry to bother you but I'm having problems compiling the kernel (I'm newbie). Once I do "make menuconfig", "make", "make modules_install", I issue the "make install" command but says:

Can anyone help me?

I have HP ENVY x360 2-in-1 Laptop 15-ew0xxx. Is there any patch to fix the sound for this machine. I am using ubuntu 22.04.4 LTS

[luxwarp]

Easiest way is if you install latest kernel 6.9 how ever it's still in rc version 🙂

[adkarpov]

how would i do this on linux exactly? some basic steps would be nice to see.
