Internal speakers' sound reduced after Windows 11 23H2 update on ROG Strix SCAR 16 (2023) G634JZ

[SHEDEVR]

Hello! I have an ROG Strix SCAR 16 (2023) G634JZ. Previously, I was using Windows 11 that came pre-installed by the store where I purchased the laptop. Recently, I installed the latest Windows 11 2024 23H2 with updates. I seem to have installed all the necessary drivers. I updated everything via MyASUS and Armoury Crate. However, the sound from the internal speakers has become quieter. It seems that the maximum volume is the same, but if I lower the volume slider to 30-40%, the sound is barely audible. Previously, it was loud at that level.

I searched online for solutions. I even uninstalled the Realtek driver, but nothing helped.

I asked ChatGPT for advice, and it suggested installing an amplifier driver. Maybe I need to install AudioWizard? I don't have it, and I couldn't find the installer online. It's also not available here:

Could you please advise on what the problem might be? Could the latest Windows update have lowered the sound, or do I really need to install an amplifier driver? Does my laptop even have one?

By the way, I noticed that a Cirrus driver appeared in the system, which wasn't there in the previous Windows version.

Thank you!

Hi! Yes, I solved the problem. It turned out that Dolby Access had the "Music with filter" option enabled, which made the sound quieter. I disabled it, and everything worked.

But I have another issue. My monitor stopped working through USB Type C. Both USB Type C ports stopped functioning.

In the Device Manager, I found the problem: ACPI UCM-UCSI. Also, there are issues with the ports - Intel PCI Express Root Port №25 (7A48) and Intel PCI Express Root Port №9 (7A30).

I don't know what the problem is. I googled it, and it seems this is a common issue with Asus laptops.

How can I fix it?
