My explanation wasn't clear enough obviously: the file attached was NOT an original mp3 file. It was a convenient way for me to enable you to hear how the mp3 played in mpg321 on my system. The file I sent was the result of the original mp3 file played in mpg321 with -w switch and encoded back in mp3 since the wav file was too big to send by email. I should have also included the original mp3 file but I didn't feel comfortable with sending a copyright-protected song on a mailing-list. > > I have attached to this reportbug a sample of a mp3 file where you could >hear the problem.

Definitely not, what you hear is what I hear when I play the file with mpg321 (the file works fine with other players). The application I use to create the wav file is mpg321 and lame for the mp3. The resulting mp3 corresponds to what I hear. > There are no changes regarding the audio stream or audio output between > 0.2.11-3 and 0.2.12-1.

New information: I have tested it with 0.2.12-1 on my amd64 debian box, there is no problem. It means I have this problem only with the version of mpg321 debian ppc. Are you sure there was not evolution between audio output between 0.2.10.6 and 0.2.12-1? In the dependencies, I can see that libao2 was formerly used, now it is libao4. I could therefore be a problem with one of the new dependencies in 0.2.12-1 and not mpg321 directly but I cannot be sure. I don't know if I can do more tests to help you, please tell me if it is the case. Best regards.
