I've had a better look at this today, and it seems that it could be what we need. It's for the sun4i and exdroid - which the Excel references in its firmware .
However it looks like the firmware would need to be decompiled and then recompiled with this in it - (that is way over my head). Also it might not have fixed the sync issue as there are references to fw 2.01 and I have read elsewhere (slatedroid, I think) - that people with this FW version still had the issue.
We do seem to be getting closer, from looking at the file it is referencing codec's. I am still hoping that someone with an Excel with 4.01, will look to see if they have the files I mentioned and few posts back on this thread.
