Have you ensured both users are using the same e2ee key?

Yes, audio decoding is normal a few seconds after joining the meeting.
I guest the reason:
when user join room, the sub signal and media stream frist recived, but e2ee FrameDecryptor enable sync later. so a small segment of the audio was not decrypted.
