About Windows Bluetooth headset audio encoding solution

How can I check which audio codec is currently being used when connecting Bluetooth headphones to a Windows 11 computer? Does anyone know? My network card is ax211, which supports aptX, and my headphones also support aptX, but I don't know if aptX is being used when connected. Is there a way to check?

    Adjust the audio encoding format in Settings > Bluetooth & devices > Device properties, or update the Bluetooth driver to support aptX/LE Audio.
