Sound settings are set for these values: Master Gain - 0.9 Music Gane - 0.2 Ambient Gain - 0.6 Action Gain - 0.7 UI Gain - 0.7 Seemes OK. I found some strangeness: /usr/share/games/0ad/mods/public/ directory hasn't subdirs, only one archive file "public.zip" that contains some data including sounds. I do not know should be this archive extracted or not. I extracted archive content and tried to start game, but it doesn't help. Any way to get some additional info on this issue? Is it possible to run in debug mode? If so, how do I do it?
