I'm not sure, if it's just the problem in selection in the GUI or the fact, that tileset is changed at runtime...

Keys: yesterday I had no problems with input. I'll have an eye on that , amybe I get a clue, in which situations that happens...

Sound: I have stdsounds directory inside my FreeCiv directory. In FreeCiv sound output is set to "sdl".
but no sound.
Other SDL based Games however have working sound output.
