Thanks tnmats! It did the trick. I changed to North America and the Volume setting is there and it’s possible to choose between ‘Normal’ and ‘High’. That’s exactly what I was looking for. When you select Europe this setting is unavailable for some reason. It must be a bug because I am sure it was there in the previous version even when selecting Europe - I am based in UK and have never selscted North America before.
As for Replay Gain I don’t feel like I am gonna use if it requires any extra work. I just though it was a slightly more sophisticated setting to boost the volume that replaced a previous Volume setting I couldn’t find.
Anyway, thanks again for your help guys! Much appreciated!
