Inspiron 3501 Cirrus Audio Issues

After updating Windows 11 to 24H2, I encountered audio issues. When the computer enters sleep mode, the audio service disconnects, producing distorted sounds like scratching noise. I attempted several solutions, including reinstalling the Cirrus audio drivers via Dell’s support and the device manager. While the audio temporarily worked, the drivers occasionally disappeared. Restoring the system to the previous Windows version didn’t resolve the problem, and the issue persisted. Additionally, the BIOS was updated during the Windows update, but attempts to downgrade the BIOS didn’t fix the issue. The only component that couldn’t be downgraded was the ME firmware.

Currently, audio functions correctly after restarting, but only for about four minutes before the distortion reoccurs. Both headphones and Bluetooth speakers are affected. Despite having the latest Cirrus driver version provided by Dell installed, there are no further updates available. I also tried a factory image restore, but the issue remains. This suggests the problem could stem from either the BIOS or a miscommunication between the driver and Windows. Immediate assistance is needed, as this significantly impacts productivity.
