Package: libao4
Version: 1.0.0-4
Severity: important

Hello,

After upgrading mpg321 from version 0.2.10.6 which uses libao2 to version 
0.2.12-1 which uses libao4, I started having the following problems when 
playing a mp3 file:
- high-level noise in the background
- sound deformation especially on voices.
I first filled a bug report for mpg321 (bug number 588531) where I have 
attached a mp3 file which corresponds to the output sound of my system (having 
mpg321 write a wav file then I converted it to mp3)
(http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=5;filename=Sample_output_mpg321.mp3;att=1;bug=588531)
If you listen to the mp3 file, you will be able to hear the problems.
However, after a discussion with the mpg321 maintainer and a few tests (he sent 
me a short code using libao to play a wav file), we identified that the problem 
came from libao4.
Wav files play just fine when the code is compiled against libao2 but the 
problems I have described appear when it is compiled against libao4.

This problem only occurs on the debian-ppc version (it works fine on my amd64 
debian desktop).
If that seems relevant, could you merge the previously filled bug report for 
mpg321 (588531) with this new one?

Please tell me if you would need more information.
Best regards.

Jad
