Please describe the problem:
Certain MP3 files I play using Rhythmbox/Gstreamer 0.10.3 constantly produce a
terrible, somewhat low frequency 'popping' sound, this appears to occur at
certain frequencies only (it is not relating to my speakers). This is not new
to me, as I have heard this behaviour before in some early Windows based MP3
players too, but that had since gone. The problem seems to now have re-emerged
in GStreamer. It only happens on some MP3 files as far as I can see, and not on
OGG files, so it has to be something to do with the MP3 plugin. I am
particularly hearing this 'popping' sound on the free MP3 songs by 'Generation
Trance', downloaded from http://generationtrance.com/mixes.php?showcat=3 I am
currently listening to 'Voices of Winter 2004', which produces the 'popping'
sound described. I am using good quality speakers and audigy 4 sound card, and
I am not running the speakers too loud, so it has nothing to do with that, the
popping sound is even produced on low volume settings.

Steps to reproduce:
1. Use good quality speakers, so the popping sound can be heard easier
2. Download an MP3 by 'Generation Trance', or use another MP3.
3. Play in Rhythmbox and listen carefully for popping sound.


Actual results:
I hear a low frequency popping sound on and off, on certain frequencis

Expected results:
The sound should be clean, as it is when playing the same MP3 in
Winamp/Windows.

Does this happen every time?
Yes
