Hello SakibIshmam,
Thank you for reaching out in Apple Support Communities. We understand that the option to select spatial audio is grayed out via Control Center on your iPhone XS with your AirPods Pro. We'll be happy to help.
Just to be sure, let's verify that your iPhone XS has the latest version of iOS 15.3.1 installed. If needed, you can find that information by going to Settings > General > About > Software Version.
If you're on the latest version of iOS 15.3.1, please answer the following questions:
- Are you noticing that spatial audio is grayed out for a specific app? If so, which application is this occurring on?
- What is the firmware version for your AirPods Pro? To gather that information, you can go to Settings > Bluetooth > tap the "i" for your AirPods Pro > Version.
We look forward to hearing back from you with an update.
Best regards.
