Changing buffer content

Hi!

I'm creating a voice chat and am using OpenAL for the output. The Problem that I currently have is, that if I change the content of a buffer of a source and play it, I can't hear anything.

Code:
//--------------------------------------------
alSourceStop(soundsOut_current->source);
alBufferData(soundsOut_current->buffer, AL_FORMAT_MONO16, decoded_buffer, voice_Bufsize, voice_SamplesPerSecond);
alSourcei(soundsOut_current->source, AL_BUFFER, soundsOut_current->buffer);
alSourcePlay(soundsOut_current->source);
//--------------------------------------------

Everytime I receive a packet with new data, I want to play it with the code above. Because I don't want to initialize a source and buffer for every received packed I want to change the content of the buffer only. But I simply hear nohting...

What am I doing wrong?

Thanks for your help!
