I just received my H10 from a Chinese supplier. It's a very nice solid piece of kit and seems to work well. I had to play around with the Sound settings on my pc a bit - set the sound output to my Samsung TV to 5.1 as the H10 reports/merges the AVR EIDE to the TV - so 2.0 becomes 5.1 - magic! Question is, how do I know which firmware the H10 is on? Quite likely v2 as the unit is new & just purchased but how to tell please? Also, how do firmware updates work? Thanks
