Problem: USB Type-C Headphones Not Working After Kernel Flash on Samsung S24 Ultra (S928b)

You've flashed a new kernel (6.1.75) on your Samsung S24 Ultra (S928b) and now your USB Type-C headphones aren't working. Even though they functioned flawlessly with Magisk, they're now silent. This can be frustrating, but don't worry, there are steps you can take to diagnose and potentially fix the issue.

Here's a breakdown of potential causes and solutions:

Driver Issues: Kernel flashes can sometimes disrupt or remove necessary drivers.

Check for updated USB audio drivers. Your manufacturer or kernel developer may have released updated drivers specifically for this kernel version.
Try reinstalling the USB audio drivers completely. This might involve using a driver uninstaller tool to remove any existing drivers and then reinstalling fresh ones.

Kernel Configurations: The new kernel might have settings related to audio output that are conflicting with your headphones.

Investigate your kernel's configuration options. Look for settings related to USB audio or sound output. You may need to adjust these settings to match your headphones.
Consult the kernel documentation or community forums for guidance on configuring audio settings for your specific kernel.

Magisk Interference: While your headphones worked fine with Magisk, there's a chance the kernel update has caused incompatibility.

Temporarily disable Magisk. See if your headphones function without Magisk active. If so, you may need to find a compatible Magisk module for your new kernel or adjust Magisk settings.
Device-Specific Issues: There might be a bug or incompatibility between your phone's hardware and the new kernel.

Search online forums dedicated to your device model and the specific kernel you've installed. Others may have encountered similar issues and found solutions.
Contact Samsung support or the kernel developer for assistance. They may be able to provide more specific guidance or identify a known issue.

Remember to back up your data before making any major changes to your device's software or settings.
