Persistent audio issue after sleep – Cirrus Logic Code 10 (GA403UI)

[TimDore]

Hello,

I’m encountering a recurring audio issue with my ASUS ROG Zephyrus G14 (2024 model, GA403UI). I’m posting here because after extensive testing and reinstallations, I’m leaning toward a hardware-related problem. English is not my native language, so I hope this message is clear enough.

The issue started after waking the laptop from a long sleep. The internal speakers suddenly began sounding distant and muffled. I checked Device Manager and saw that the “Cirrus Logic Awesome Speaker Amps” device showed a Code 10: “This device cannot start” (ACPI\CSC3556). The driver involved is oem32.inf.

This is not the first time this happened. A few months ago, the same issue appeared. Back then, simply disabling the audio device, updating the driver, and re-enabling it was enough to fix it temporarily. However, this time, that workaround no longer helps.

Here’s what I’ve done so far:

• Reinstalled Windows 11 cleanly from a USB stick, fully formatting all partitions

• Performed the installation offline (no internet) to avoid interference from Windows Update

• Manually installed all ASUS official drivers in proper order, starting with the chipset, then I2C, audio (Cirrus Logic, Realtek), Dolby, etc.

• Disabled automatic driver installation via Windows policies

• Used Driver Store Explorer (RAPR) in Safe Mode to fully clean out all old and conflicting drivers

• Tried several driver versions, including the most recent one (v25) and older ones

• Tested the machine using a live USB with Ubuntu Linux (24.04). The sound under Linux was also distant and very low, just like in Windows

I also generated an ALSA info report under Linux:

http://alsa-project.org/db/?f=df84f99eaf6a88d9692aff9b94f08f732e969972

The report shows that the audio codec (cs35l41) is detected and loaded, but no output audio device seems active. Although nothing in the report explicitly states that the hardware is broken, the fact that the issue persists across two different operating systems with different audio stacks (Windows and Linux) strongly suggests a low-level hardware malfunction. Possibly a failed amplifier or a signal routing issue on the board.

The laptop is under warranty until December 2025. I live in French Polynesia, and the unit was purchased at Best Buy in Costa Mesa, California. I’m seeking advice or confirmation from ASUS or the community about how to proceed with support and warranty repair from my region.

Thank you very much in advance for any help or insight.

Thank you for the detailed information. Based on your testing, it does seem necessary to further inspect the hardware to clarify the issue. We are unsure if you have tried the following: in the Cirrus AMP device properties > Power Management, disable the option "Allow the computer to turn off this device to save power", then test if the issue improves.

If the problem persists, based on your description, since the device was purchased at Best Buy in the USA, it does not have international warranty and can only be serviced under warranty in the USA. If you are only temporarily staying in French Polynesia, we recommend that you bring the device back to the USA and then apply for an RMA for hardware inspection.

If you will be staying in French Polynesia long-term, please note that since the device does not have international warranty, any inspection and repair in French Polynesia will be subject to charges. We recommend that you contact the local service center there to apply for an RMA service. The above information is provided for your reference. Thank you.
