Can't GetData from AudioClip that load from UnityWebRequest even thought it has been set stream=false and compressed=true

Hello, i wanna ask a question about AudioClip in Unity.
When i try to GetData() from AudioClip that i load from path using UnityWebRequest it give me error: “Cannot get data on compressed samples for audio clip “”. Changing the load type to DecompressOnLoad on the audio clip will fix this.” But when i open the file from UnityWebRequest i have enable compress and stream to false. Does anybody know how to fix this?
