Danna:
I can't quite get there from here <grin>.
In the Control Panel, I have "Sounds, Speech, and Audio Devices".
That window shows: "Pick a task" then
- Adjust the system volume
- Change the sound scheme
- Change the speaker settings
I checked all those, none require attention.

The same window with Pick a task, also shows:
"or pick a Control Panel Icon" with the choices
- Sounds and Audio Devices (brings up a window I've already checked)
- Speech (brings up a Text to Speech window)
- Realtek HD Sound Effect Manager

The last one held more promise as it has a Mixer tab showing settings for both Playback (don't need, it works fine) and Record. The Record area shows sliders for Mic Volume Line Volume and Stereo Mix, with an enable radio button for each (only one can be enabled at a time).

It was set to "Mic Volume". I changed it to "Line Volume" and tried the record process again in Audacity. Still nothing.

Am I even in the right place here?

I also found a window by right clicking the Volume icon in the bottom icon tray, and selecting Open Volume Control. All volumes are up, nothing muted, no right-click-in-window option available.

But when I click on Options and select Properties, it shows the "Mixer device" as "Realtek HD Audio output" and "Adjust volume for - Playback (button enabled) but the "Recording button is greyed out. Could this be the problem?

Thanks for your help!
