Some laptops - in particular my Dell Studio XPS - have two headphone ports.
Under Windows 7 currently the last pair of headphones plugged in begins to accept the output.
Is there something special that needs to be configured to allow both headphones to operate simultaneously?
What I have tried:
- Setting both as "default" - not an option (can't multi-select).
- Toggling the "default" - it just switches the active headphone.
- Toggling disable and enable - didn't help.
