When `MediaPlayer` plays [http://app.readspeaker.com/cgi-
bin/rsent?customerid=4839&lang=nl&save=1&url=http%3A%2F%2Fwww.ns.nl%2Fgeleidelijnen%2FshowGeleidelijn.do%3Fstation%3Ddv%26arrival%3Dingang_busstation%26departure%3Dspoor_4a%252Bb&audiofilename=geleidelijn.dv.ingang_busstation.spoor_4a%2Bb
the tested mp3 file] the first time, it sound normal. However, repeated
plays causes distortion.
Steps to reproduce:
1. Play [http://app.readspeaker.com/cgi-
bin/rsent?customerid=4839&lang=nl&save=1&url=http%3A%2F%2Fwww.ns.nl%2Fgeleidelijnen%2FshowGeleidelijn.do%3Fstation%3Ddv%26arrival%3Dingang_busstation%26departure%3Dspoor_4a%252Bb&audiofilename=geleidelijn.dv.ingang_busstation.spoor_4a%2Bb
the tested mp3 file] in `MediaPlayer`
- notice that the sound is normal
2. Press `space` to play it again
- notice that the sound is slightly distorted
3. Press `space` to play it again
- notice that the sound is heavenly distorted (sounds like an inverted
echo)
It might take a couple of repeats longer to get the heavenly distorted
sound.
Tested on r38581 with an `Emuxki SB Live 5.1` sound card (real-time audio
enabled).
VLC plays the mp3 fine no matter how many times it repeats.
Output from `MediaPlayer` when playing the file:
