java - Audioclip: javax.sound.sampled.LineUnavailableException

Question

Im trying to play a file to my speakers using AudioClip. To mention i run this on a docker container

Here i get the audio file info from my server and tried to play it.

int length = fromServer.readInt();//takes audio file length from socket
if (length > 0) {
  byte[] message = new byte[length];
  fromServer.readFully(message, 0, message.length);//reads the data in socket into array "message"

  AudioInputStream oAIS = new AudioInputStream(
  new ByteArrayInputStream(message),
  new AudioFormat(44100.0f, 16, 2, true, false),length); 
  //creates an AudioInputStream which can be used for playing the data
  AudioPlayer.main(oAIS);
 }

When my programm enters this function i get

javax.sound.sampled.LineUnavailableException
