WIndows 11 ARM64 install on Snapdragon

Welcome elnino,

I understand how frustrating it can be when you successfully installed Windows 11 ARM64 on a Snapdragon-based laptop using a custom installation method, but the touchscreen and audio are not working. 

Before we continue, could you please confirm:  

• Could you please share the exact laptop model? 
• In Device Manager, are there any devices showing a yellow warning icon under Audio inputs and outputs, Sound, video and game controllers, or Human Interface Devices? 

In the meantime, you can try these steps below to troubleshoot the issue:  

Step 1: Check for ARM64 driver availability  

• Open Device Manager from the Start menu 
• Note the names of any unknown devices or devices with warning icons 
• Select Properties > Details > Hardware Ids and record the IDs 

Step 2: Install Windows updates  

• Open Settings > Windows Update 
• Select Check for updates 
• Install all available updates, including optional driver updates 

Step 3: Scan for hardware changes  

• Open Device Manager from the Start menu 
• Select Action > Scan for hardware changes 

Step 4: Review audio device status  

• Open Device manager from the Start menu 
• Expand Sound, video and game controllers 
• Check whether any Qualcomm audio device appears 
• If present, open Properties and check the device status 

I hope the steps above help you deal with your issue.
