i can confirm this bug. Latest feisty, no old packages. Switching to the ffmpeg library works around the screeching sound.

The sound is decoded at the right speed. -- [Feisty] mplayer fails to play mp3 audio correctly with mp3lib https://launchpad.net/bugs/86513 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
