Comment (by bat999):

 Hi
 The "3043.live.streamtheworld.com/SAM04AAC41_SC" stream is no longer
 active.
 Is there an alternative stream to test instead?

 Maybe the attached file "SAM04AAC41_SC" corrupt.
 Latest FFplay seems to play similar files OK.

 Format/Info       : Advanced Audio Codec
 Format version    : Version 4
 Format profile    : HE-AACv2 / HE-AAC / LC
 Bit rate mode     : Variable
 Channel(s)        : 2 channels / 1 channel / 1 channel
