Description
In some S60 devices the level of background noise may be disturbing when using an audio output stream to play back silence; that is, when the stream is fed with zero-filled buffers.
Solution
Applications should not implement a 'mute' functionality by streaming zero-filled buffers. Instead, the output stream should either be stopped or its volume level should be set to 0.
Note that adjusting the volume is a significantly faster operation than stopping/ restarting the stream.
