ASUS ROG Zephyrus M16 2023 - Weak Speaker Sound

[marcvg]

Summary

Hi,

There is a known issue with the Cirrus CS35L41 amp inside to drive the bass/mid-range speakers. Unfortunately the driver for it won't use it as it is missing a series of properties stored in the _DSD of the ACPI.

Information & fix patch: https://asus-linux.org/wiki/cirrus-amps/

Is this something that can be supported/enabled OOTB in Solus for these 2023 ROG laptops? I'm sure more people will encounter this issue until fixed upstream.

Cheers, Marc.

Steps to reproduce

1. Create Solus 4.4 Live-USB
2. Boot on ASUS ROG Zephyrus 2023 laptop (or any laptop with Cirrus CS35L41 amp)
3. Play some techno music

Expected result

Hearing full sound

Actual result

Hearing low volume chirping noises

The kernel support for this will be in our 6.6 kernel

FYI.. sound is working after applying _DSD patch with latest kernel 6.6.7 & firmware updates. Thanks @ReillyBrogan @HarveyDevel
