Hi FlashElangbam,
I'm Benedict, an Independent Advisor. I'm here to help you.
Kindly try running the Playing Audio Troubleshooter (if you haven't tried this yet) in Settings>Update & Security>Troubleshoot, or to locate this (do this while your audio output device is connected to line out):
- Open Start Menu.
- Type and search for "Troubleshoot settings". Open it.
- In the right pane, if you can't see the said troubleshooter or no recommended troubleshooter is listed, click on Additional troubleshooters.
- Now, look for the said troubleshooter and click it.
- Click on "Run the troubleshooter"
If that doesn't help, kindly try updating manually your line out/audio output driver in Device Manager:
- Open Start Menu.
- Type Device Manager and Open it.
- Double-Click on the category "Audio inputs and outputs".
- Right click on your audio output driver and select "Update Driver".
- Next select "Browse my computer for drivers"
- Click on "Let me pick from a list of available drivers on my computer".
- Make sure the option "Show compatible hardware" is checked.
- Select Generic device and click Next. Check and see if that fixes your line out audio issues.
Hope that helps.
Regards,
Benedict P.
