Decrease audio receive buffer

A few months ago I suggested to decrease the audio buffer size #2 Because there was another buffer in between it hadn't much effect. However CAPABILITY_DIRECT_SUBMIT @a41ccad8cf0 has changed things. With a bitrate of 96kbps the current buffer could hold 5 seconds of audio. While there is every 8ms a new sound packet Java can't catch up so I allow a delay of 100ms.
