Is it possible, through some adapter/converter, to connect a usb headset to a device which only has an optical output port. The device outputs 5.1 dolby surround, which I'd like to enjoy using the headset.
All such adapters I can find seem to do the opposite transcoding...
Don't quote me on this, but there's likely a dongle attached to the USB chord of the Headset, which if the Headset is in fact True 5.1 Surround Sound will already natively support 5.1 Surround Sound through said dongle.
If you're talking about Virtual Surround Sound there are quite a few 3rd party programs that allow you to emulate the effect with stereo Headsets.
