Ok so here's details of the difference between EDO 0.6 and 0.7 and the
two binaries for people believing there is a difference.
1st - a diff between the two install zips:

--------------------
This shows that other than the difference in the binary file jive_alsa,
the only difference is the new menu options and the display strings for
this. If you don't select these very large buffer values then this is
not used and not relavent.
2nd the binary jive_alsa, I've just confirmed the binary builds again by
rebuilding them and the only difference is the following patch (see the
rest of the code in my github repo posted a few posts above):

--------------------
I've attached the two jive_alsa binaries in the zip file attached - if
you want to manually try these then scp this file them to Touch, unzip
the file and copy them one at a time to /usr/bin/jive_alsa, "sync" and
"reboot". I think you will find they do the same thing except in the
case when you get the "Reopening device %s in plug mode as %s" message
in the log which is only for low sample rate internet radio stations.
In short - don't see any meaningful changes.
