Version prior to SR3 just released.
Read Aloud reads greek fine from NA27, just as it did for Logos4 (Windows Vista PC).
On NA28 last night, it does not detect its greek so passes the text to Windows to read as if it was English, so of course the result is a total fail.
I'd guess there is a missing flag, tag or metadata thingie in the new NA28 to trigger the Read Aloud to NOT use Text-to-speech, but play the greek audio file. I had purchased the Greek addon way back, and its still active as it works for NA27, hence my guess its the metadata for the new resource. I've not yet tested what it does on the various other greek texts I have.
Maybe this is not the most critical bug in the world: just saying so it goes on the list please.
