*** 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
[...]

The versions of related programs and libraries where this happens for me
are:
libasound2-plugins 1.0.27-2
libavcodec53 6:0.8.7-1
libavutil51 6:0.8.7-1
pulseaudio 4.0-3 || 2.0-6.1
I hope the provided information is sufficient to reproduce and/or
isolate the bug. 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. Thanks for your great
work, and Best Regards
