|Background noise while streaming zero-filled buffers||KIS000656|
|Reported against||S60 2nd Edition and FP1, FP2, FP3|
S60 3rd Edition and FP1
|Date identified||May 21, 2007|
|Detailed 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.|
|How to reproduce||-|
|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.
