Status changed to 'Confirmed' because the bug affects multiple users.

[Johan Foolson (johan.foolson)]

Seems to be a downstream issue.

I downloaded the same package version but from the repos for Debian Sid and it works.

Looks like the codec doesn't reference/load libopus0 properly.
My *workaround* for codec_opus_open_source (as root):

service asterisk stop
OPUS_LIB_LOC=$(dpkg-query -L libopus0 | grep '.so.0$') # to support multiarch
mv /usr/sbin/asterisk{,_orig}
echo -e '#!/bin/bash\nLD_PRELOAD='$OPUS_LIB_LOC' exec /usr/sbin/asterisk_orig "$@"' > /usr/sbin/asterisk
chmod +x /usr/sbin/asterisk
service asterisk start

My workaround is to create an override for asterisk service unit:

# /etc/systemd/system/asterisk.service.d/override.conf
[Service]
Environment=LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libopus.so.0

This is an ubuntu-specific issue. I fixed it as described here: https://lists.ubuntu.com/archives/ubuntu-devel/2010-November/031991.html

[Dmitriy Rodin (p1p)]

Previous patch does not work because pbuilder redefines LDFLAGS. Fixed.
