I’ve done everything right. I have “Speakers and Headphones” set as my default device. I have “Allow programs to take exclusive control of the device” unchecked. The sound works fine with every program that I use. The audio drivers are updated. I get no sound from Audacity. I can see the audio playing, but I’m getting no sound from my speakers. I’ve checked all over the net for a solution and the only thing that they ever suggest is what I’ve done already. Is there some kind of comparability thing going on here?
I’ve tried using the MME driver, and the Windows Directsound driver as well and I still get no audio.
There are two places to set it, Windows Control Panels and Audacity Preferences. Do they match?
Audacity > Edit > Preferences > Devices > Playback > Device.
Do you get any other error like “Unable to open device…?”
Are you using a USB microphone and does it start working if you unplug it and restart Audacity?

Yes. They match. Speakers and Headphones is set as my default device in both.
When I load up an audio file in Audacity, I can see it playing. The audio level bar is bouncing back and forth like it should, but I get no sound out of the speakers.
There is no error message and I’m not using a USB microphone.
Audacity is the only application that I have that isn’t sending the audio to the speakers.
In Audacity, Generate > Tone > OK .
Turn the Audacity output slider up in Mixer Toolbar (the right-hand slider here):

Play the tone.
While the audio is playing, click the speaker icon by the system clock, then choose “Mixer”. Ensure the Audacity volume slider is turned up and unmuted.
If none of that helps, try rebooting the computer.

That was exactly the problem. The volume slider was defaulted to all the way down to the bottom.
OK I marked the topic as “Solved”.
Audacity doesn’t actually have any intended control over its slider in the Windows Volume Mixer. It operates directly on the “Device” slider (the system slider for the output device).
