The sound crackles badly when playing certain files. It has occurred for two of my sound files.
Set the equalizer to its default settings.
play the attached file.
If you change the settings to the same as my previous bug i submitted, the whole sound is attenuated (not so bad as the file submitted in the last bug) and the crackling is probably hidden. The whole sound is not attenuated if the last slider frequency is not modified (still at -100dB) - but the crackling is heard.
