I updated to 5.3, it went easy as always.
Did not notice anything different, all seemed to work just fine (as always)
Got complaints yesterday that there was no sound on my stream (remote scanner over ip).
I've checked it all this morning, hardware, cables etc, i could not find anything wrong and there was sound on the web server but there was no sound on the remote scanner over ip.
Came over here, saw that there were some issues with 5.3..rolled back to 5.2 and voila there was sound.
(got a bit of a bald spot though from scratching my head in confusion
