iOS Audio Crackling issue when send audio data to UDP server and Play

I am experiencing an issue while recording audio using AVAudioEngine with the installTap method. I convert the AVAudioPCMBuffer to Data and send it to a UDP server. However, when I receive the Data and play it back, there is continuous crackling noise during playback.

I am sending audio data using this library "https://github.com/mindAndroid/swift-rtp" by creating packet and send it.

Please help me resolve this issue. I have attached the code reference that I am currently using.

Thank you.
