Question Can't adjust line-in audio in Windows 10?

[delatroy]

Hello.
I have a PS4 line-in going into my sound card on my motherboard. I'm listening to the line-in through my headphones. Everything works great but I cannot control the volume. Moving the slide up / down in the sound mixer has not affect at all. Anyone know what I can do?

Try the audio troubleshooter. Right click on the windows symbol and chose search (or use search in the taskbar) and start typing "trouble". The troubleshooter app will appear and click on it. In the Troubleshooter screen, click on Audio. If that doesn't work search for "Blue" and click on the Bluetooth and other devices app (it's not just for Bluetooth). Remove the audio device and then click add Bluetooth or other device and reinstall the audio device.
