I am a new user. I created an audio file and exported as MP3.
Downloaded appropriated LAME files.
When I play the MP3 file, I get no sound. Tried playing the file on different players.
What am I doing wrong?

If you recorded from a USB cassette player, USB turntable, or similar USB device, see here:

I used FOcus 2i2 as input with a mic attached. OUtput to speakers.
Playback worked fine.

solution to reset default device worked. Thanks.
