--- Begin Message ---Package: libavutil51 Version: 6:0.8.7-1 Severity: important Tags: upstream Dear Maintainer, *** Please consider answering these questions, where appropriate *** * What led up to the situation? * What exactly did you do (or not do) that was effective (or ineffective)? * What was the outcome of this action? * What outcome did you expect instead? *** End of the template - remove these lines *** I am using pulseaudio (tried 2.0-6.1 and 4.0-3) for my sound output via digital surround S/PDIF using A52 encoding. This is achieved by pulseaudio relying on libasound2-plugins encoder which in turn relies on libav (as far as i can understand). After a recent testing (my current debian version) upgrade pulseaudio began not to start anymore, and exiting with a SIGFPE, Arithmetic exception. This can (probably/hopefully) be reproduced the following way: Install pulseaudio and its libav dependencies from unstable on a computer with a S/PDIF output that can/could be used by alsa. Put the following in /etc/asound.conf: ============================= pcm.a52 { @args [CARD] @args.CARD { type string } type rate slave { pcm { type a52 bitrate 448 channels 6 card $CARD } rate 48000 #required somehow, otherwise nothing happens in PulseAudio } } ============================= and then starting pulseaudio: ~/ > pulseaudio W: [pulseaudio] pid.c: Stale PID file, overwriting. Floating point exception Digging deeper with gdb, you might get: ============================= ~/ > gdb pulseaudio [...] (gdb) run Starting program: /usr/bin/pulseaudio warning: no loadable sections found in added symbol-file system-supplied DSO at 0x7ffff7ffa000 warning: Could not load shared library symbols for linux-vdso.so.1.

By the way, one pulseaudio developer in IRC suggested to report the bug to either alsa-plugins or libav upstream. If anything more is needed, please tell me what.
