!!! NOTE: As of Linux Kernel 6.7 this patch is obsolete. !!!
Linux ProArt Studiobook H7604JV_H7604JV sound fix.
Works with:
Hardware Class: sound
Model: "Intel Multimedia audio controller"
Vendor: pci 0x8086 "Intel Corporation"
Device: pci 0x7a50
SubVendor: pci 0x1043 "ASUSTeK Computer Inc."
SubDevice: pci 0x1f1f
Revision: 0x11
Driver: "snd_hda_intel"
Driver Modules: "snd_hda_intel"Use ONLY for this specific model and BIOS version 300 (H7604JV.300) and at your own risk!
ASUS Laptops have an incorporated Cirrus CS35L41 audio amplifier.
Their BIOSes do not properly expose ACPI properties to the kernel, thus Linux drivers won't be able to use this amplifier.
This fix adds missing properties to the kernel and is based on:

Firmware has been extracted from Windows 11.
This patch has been tested on KUbuntu 23.04 with linux kernel 6.4.11-060411-generic, however it should work on any kernel supporting ASUS UX582ZS, which appears to be compatible with H7604JV.
Support has been introduced here:
https://lore.kernel.org/lkml/20220815141953.25197-1-sbinding@opensource.cirrus.com/.
To install a specific version of the kernel use: https://learnubuntu.com/install-mainline-kernel/
Install the following dependencies:
sudo apt install acpica-tools
Issue ./install.sh to install patched ACPI properties and firmware.
Add the following line to /etc/default/grub
GRUB_EARLY_INITRD_LINUX_CUSTOM="patched_cirrus_acpi.cpio"
Add the following line to /etc/modprobe.d/alsa-base.conf to tell alsa to use kernel quirks for UX582ZS, a driver that's already present and works:
options snd-hda-intel model=1043:1a8f
Issue sudo update-grub and reboot.
Potentially secure boot must be disabled.
A kernel patch should be made for quirks specific to: H7604JV.
It can be done by adding this line in linux/sound/pci/hda/patch_realtek.c:
SND_PCI_QUIRK(0x1043, 0x1863, "ASUS UX6404VV", ALC245_FIXUP_CS35L41_SPI_2),
