Bug Description

Ubuntu 13.10
libavutil51: 6:0.8.9-0ubuntu0.13.10.1
libasound2-plugins-extra: 1.0.27-2ubuntu1

After following the guide at
https://help.ubuntu.com/community/DigitalAC-3Pulseaudio

Pulseaudo crashed with a SIGFPE, Arithmetic exception just after start.

The same bug in entirely analyzed here http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=713856

It turns out that libasound2-plugins-extra: 1.0.27-2ubuntu1 expects version 9 of libavutil , because it uses 0 for default alignement which was introduced after 0.8.9 release.

It looks like the issue was fixed by back porting
http://git.libav.org/?p=libav.git;a=patch;h=0109a09dc3850eb5dbff84a7bb50eb252a5a8f22
to 0.8.8.

We need it for 0.8.9 as well.
