I found the same thing with aac and wmv.
Already reported it a few months ago.
But that was during the whole ffmpeg/libav incident so it probably got
wasted.
Just took your post as reason to repeat the ticket:

When seeking in a mp3 file, the decoder produce a noise depending of
when the seek is done. This is illustrated in the attached file
"audioBitStream.jpg".
->If I seek to timestamp 0 while playing "hight" sound, a noise is
clearly visible when I restart decoding (see first stereo stream :
dump10noise.raw)
->If I seek to timestamp 0 while playing "silence", no noise is
produced (see second stereo stream : dump10clear.raw)
So it seems that avcodec_flush_buffers doesn't completely flush all
the buffers of the codec. We see that it keep track of the last
decoded sound.
So is this a bug ? Or it's me that have I missed something?
