Just wanted to let you guys know that after a good night of computing I was able to manually edit the 3.10 source files with the difference in this patch
http://www.rockbox.org/tracker/12074 and now have a good working line out option on my Sandisk Sansa Fuze v2 with the latest 3.10 Rockbox software.
Thanks very much for the great stuff here and the great manuals and wiki's.
Ted
