Thank you for posting on the HP Support Community.
After reading your post, I did go through the motherboard specifications, Lincs spec of your product and found that you have Audio Codec: Realtek ALC3601 Audio jack presence detection however no presence of internal mic. I would recommend you can use an external mic in order to avail microphone features.
Hope this helps! Keep me posted for further assistance.
