sysread and syswrite (rather than print) let you avoid bufferring by stdio. I suggest you should be using it on both sides as you don't want stdio to be involved buffering. It would seem logical to read/write the same number of bytes rather than sending 128 and waiting on 512. You could do: 

while( sysread(CLIENT,$stream,512) ){
    syswrite( AUDIO_OUT, $stream )
}

These simple steps may or may not resolve you issues.

Buffering only helps if you 1) get ahead of the game and 2) stay ahead of the game (unless you got far enough ahead to start) of course. Depending on the behaviour of aplay you could possibly just buffer X bytes to start, send that to aplay to fill its buffer, and then loop as above. This would only work if aplay accepts the entire initial stream without blocking so that the following loop is effectively just running in top up mode. Failing that you may need a dedicated local reader that can buffer and supply a consistent stream to your writer as suggested by Zaxo
