Topic: help getting pjsua / pjsip working on BB8

i built the pjsua package on my bb8 except it can't find any audio devices.  i get this error:

pjsua_media.c  Error retrieving default audio device parameters: Unable to find default audio device (PJMEDIA_EAUD_NODEFDEV)

some time ago, duane from chumby wrote that they've used pjsua on a chumby before http://forum.chumby.com/viewtopic.php?pid=10955#p10955 and someone years later ran into the problem i'm having, but nothing further was posted.

anybody ever get this working? or duane or anyone @  chumby, can you offer some insights on getting this working?   i've gotten it to register w/ my asterisk server and i can call it but w/o sound can't do anything w/ it and of course, can't call out.

thanks!
