Export audio no sound

Sorry, I am new to Cubase.
I have no idea what I have done wrong.
The first day I played around Cubase I actually could make audio files. But the next day all files are not sound. I tried different settings in export but still no sound. I am only trying to record bass guitar and drums playing. now only down to recording sound.

There is audio from the monitor and from the tracks recorded but no sound in the exported file.

Thanks for any help


The Monitor button (orange speaker) is enabled on the track. Disable it, please.

thanks a lot
all solved now
