It is better to start a new topic than attach to someone else’s topic, so I started this for you.
I suggest you try enabling the line-in in “Sound” in Windows if you have not already done so. it is better to say exactly what you have done so far, the more detail the better.
To enable line-in in Windows:
- Make sure the line-in cable to the blue input fits tightly
- Right-click over the speaker icon in the System Tray > Recording Devices
- Right-click anywhere inside the Recording tab and choose “Show disabled devices” then right-click again and check “Show Disconnected Devices”
- Right-click specifically over the line-in, choose “Enable”
- Right-click once again over line-in, choose “Set as Default Device”
- Right-click once again over line-in, click Properties then the “Levels” tab and ensure the volume slider is turned up and unmuted
- Click OK
- Restart Audacity.
If line-in does not show in Windows, your audio drivers are probably incorrect. See here for help Missing features - Audacity Support .
