Hi AiramH, sorry for the delay getting back to you. If you are working with a known good headset, does it have one 3.5mm jack on it or is it a USB device?
If it is 3.5mm, you will need to split the signal with an adapter of some nature, and plug it into your headphone port and your microphone port separately. Your notebook does not appear to have a combo port capable of splitting the headphone & microphone signal, so as a result it will only function as headphones. This would explain why your headphones are not able to record audio.
If it is a USB device you will likely have to set your playback and recording devices to match the headphones.
Here is some more troubleshooting on the original issue.
