Do I Really Need to get a Broadcom Card for Airplay?

SMBIOS Mac Model is ' MacPro7,1 '

This is the hardware I'm working with:

• Tuf Gaming B550 Plus WIFIMotherboard
• Ryzen 7 5700X cpu
• RX 580 8Gb Sapphire edition gpu (still unable to fix DRM even though I found my GPU path, and tried setting shikigva=80 and 128 for the hell of it)
• 32 Gb of DDR4 RAM
• have intel WiFi and Bluetooth (both working fine and able to discover other networks and other bluetooth devices no problem)
• 1Tb SATA SSD

To my knowledge, MacPro7,1 should support AirPlay and Universal Control... or am I totally wrong and missing something here..?
