Hello,
I think I have the same problem as was discussed from
http://lists.jitsi.org/pipermail/dev/2014-October/022291.html to
http://lists.jitsi.org/pipermail/dev/2014-November/022558.html: Jitsi
unstable on Ubuntu 14.04 64bit finds only the "audiosilence" device.
Chatting with OTR works, but every audio or video call remains unencrypted
and no sound comes through.
I read through that thread and found the advice about JNI libraries: They
are present in /usr/share/jitsi/lib/native, but I'm not sure how much more
I can help debug this: The computer is with a relative and who I can't ask
for long TeamViewer sessions or direct via screen sharing in Skype.
Here's the first warning from the logs that seems to be relevant:
*WARNING: [13] org.jitsi.impl.neomedia.codec.FMJPlugInConfiguration.warn()
Codec org.jitsi.impl.neomedia.codec.audio.opus.JNIDecoder is NOT
successfully registeredjava.lang.UnsatisfiedLinkError:
/usr/share/jitsi/lib/native/libjnopus.so:
/usr/share/jitsi/lib/native/libjnopus.so: wrong ELF-class: ELFCLASS32
(Possible cause: architecture word width mismatch)*
Does "architecture word width mismatch" refer to a 32/64bit problem? Please
help! Jitsi was my only encrypted channel to that person 
Kind regards,
Cathryne
Yes. Did you somehow install the "i386" jitsi package? You need the "amd64" one.
Regards,
Boris

Does "architecture word width mismatch" refer to a 32/64bit problem?
Merci! Reinstalling the 64bit package worked
