i have a weird problem with the sounds of the neo geo games in gngeo,at the beginning i had sound with no problem,then i installed xgngeo and it was good through it too but suddenly i stopped hearing any sound.. i tried to open the games with x terminal but again no sound.. should i uninstall xgngeo or gngeo and reinstall them? or maybe something else..

Edit: i saw that the problem is not only with gngeo or xgngeo,i have more games without sound: marbles,lxdoom,sdl quake and all the neo geo games that i have,i only got sound in chess and mahjong but the most strange is that marbles is a default game that comes with the nokia 770 like chess and mahjong also.. i didn't touch nothing in the files inside the system and i really got no idea what can be the problem but it's driving me crazy.. if someone have some idea please let me know,thank u

Try running gngeo from xmaeme frontend, and see if you get sound.
maybe its a gngeo error.
but then again it might be xgngeo, but i don't see how the frontend could be the problem.

uninstalling might be a good choice is problem persist.
uninstall;restart;reinstall = gngeo

nothing man,i uninstalled and reintalled both xgngeo and gngeo and as i said above,the problem is with more games but thank u anyway for answer me
