How to send VLC Player audio to headphones rather than PC speaker?
This solution (from here) resolved the issue:
- Open Tools/Preferences and at the bottom of the list,under "Show settings" switch from Simple to "All".
- Under Audio, Expand and select "Output module" and change Audio output module to "Win32 waveOut extension output".
- Under "Output module" select "Waveout".
- Select Audio Device. In the dropdown, select your output used for your headset and click save.
- Restart VLC.
Note that in my case the restart of the VLC application was definitely required! It may also mean that when I previously tried various different settings without restarting VLC, the changes may actually have worked after restarting VLC.
