No audio output

Windows 10, Build 19041.630. Audacity 2.4.2. The program won’t output sound to the speakers. The speakers are working. The files play fine in Real Player. No sound when I press the Play button in Audacity, although the cursor moves indicating that the program is functioning. Thanks for any help.

Are you sure you selected the correct output device?

Thanks. That was it. There’s an oddity in my system. I have to identify the speakers as headphones. I don’t understand it. The tech guy who built the machine doesn’t understand it. But it works. I hadn’t made the adjustment in Audacity. Much appreciated.
