I installed the image on the SD card put the games in the roms folder correctly. I don't know why I have no sound in games. put it on two different smart tv's and both are without audio in games. Has anyone here experienced this and know how to solve it?

Providing logs with 

armbianmonitor -u

 helps with troubleshooting and significantly raises chances that issue gets addressed.

I don't understand, could you explain best friend

You did not state any of the mandatory information necessary to even get a chance to identify the issue you have. Therefore the bare minimum that needs to be provided by you is the output of "armbianmonitor -u".
