Windows7 uses the sound settings per program. Simutrans does usually have mono-sounds (to keep download size small). Does you talk about sound effects or midi music?

I think this is a problem in the crosscompiling since the native sound interface was not changed in between, if I remember correctly. I am also not sure how Win7 initialises the balance between both chaneels. Maybe it was set to left channel only, when the program was started for the first time?

I don´t think that this is a Problem im cross-compiling, I think a Problem of the Client (The Maschien)
I hope you understand my English

I did some more testing.
There doesn't seem to be an option in win 7 to change to stereo, but:

* I copy the entire simutrans folder
* I start simutrans from the new folder
* sound works as stereo!
* I click exit (the simutrans window, not the windows button)
* Simutrans needs some time to close (maybe 0.5 seconds), during this "closing time" I hear sound only from one speaker!
* When I start simutrans again it's only one speaker.

This is reproduceable.

This indicates that simutrans does something weird at "closing time".

Both. But its much more obvious when hearing midi music (because you hear it all the time).

Instead of copying the entire folder, one can also just rename the exe file. This seems to be the easiest workaround.

I can reproduce the issue at work (Dell Optiplex 755, Win7 64-bit).

I've found out, if you only hear the music on one speaker, go to the sounds settings in Simutrans and either increase or decrease the sound volume.  You should get it on both speakers after doing that.

This seems to be a known issue, people have been complaining on some Microsoft forums about mono sound only coming out one speaker.  Some of the issues seem to be driver related, and it doesn't seem to be specific to Simutrans.

PS: Works fine on XP.

This works for me, too.
