Cannot get any voice to work on Igo Primo Galaxy S3 - Is the

I have installed Igo Primo 9.6.22.297071 April 25 2013 on my Samsung Galaxy S3.

It works perfectly except for the fact I cannot get any voice to work? I have looked extensively on this site and I cannot find any answer? Am I to believe that it is not possible? please help I am pulling my hair out and going bald because of it.

Thanks a bunch.

There was a special jelly bean version to fix the sound issue.

I am using Android 4.2.2 Nexus rom ? After scouring the internet and other forums it doesn't look like there is a fix. (that I can see )

For anyone wishing to know how to get your IGO voices working on your android device running JB enter this line in your sys file:

[android]
navigation_audio_stream=4

Enjoy
