Can't get it to work even after all succeeding.

[rcardoso20]

Hello,

My laptop is a HP Envy 15-ew0xxx.
I'm on Ubuntu 22.04 with the Kernel 6.4.6 (6.4.6-060406-generic).

I've done all the steps, had some problems:

• With the KERNEL_VERSION since it couldn't find the "linux-image..." on dpkg (it's under "linux-image-unsigned..."), so I just declared the variable as "6.4.6-060406-generic".
• Had to change dkms-patchmodule.sh to kernel-module_patch.sh in 2 places on the file dkms-module_create.sh.
• Changed the patch line numbers to match the ones on the original file on the kernel version I mention above. (This change was not required I think).

So, this is what I've got at the moment:

dkms status
snd-hda-codec-realtek/0.1, 6.4.6-060406-generic, x86_64: installed
snd-hda-scodec-cs35l41/0.1, 6.4.6-060406-generic, x86_64: installed

After installing the 2 modules, now when I turn on the computer I hear a crackling noise that I never heard before, but, the sound is still not working.

Any suggestions what I could be missing? If there is any info needed just ask me please.
I've been walking around with this laptop for a year and I can't reproduce sound from it, only via Bluetooth :(

Hi @rcardoso20, when the speaker outputs a crackling sound I would stop using the script immediately to prevent potential hardware damage. I suppose the sound has to do with the Cirrus logic patch that might not work for your hardware setup.
That said, the "wrong filename" issue should be fixed with the newest commits thanks to @Osc100.
