Record a cassette song to Windows 10 and play it back

I have recorded one song from my cassette tape to audacity. I saved it, but when I access it, there is no sound. No, my sound is no9t muted.

Could you please help? I guess I am a little slow at this.

Thank you.

Assuming that you are using a USB cassette player, see this FAQ:
