I bought this pc https://support.hp.com/us-en/product/omen-by-hp-870-200/13687063/model/15741160/document/c05389962
A few months ago and accidentally deleted realtek audio from my pc as I didn't realise what it was for, I can now only hear sound out of one monitor at a time and when I plug in my headset I can only hear sound through the monitor and not the headset.
I've tried several times to reinstall realtek but it will not work for me at all I was thinking of buying a sound card and was wandering would that resolve my issue and on top what sound card would I buy as I would not know myself.
Thank you for taking the time too reading this and any help would be grateful

I have indeed it showed me two versions of audio drivers a 2016 and 2017 version I downloaded the 2016 then the 2017 and saw no change.
I've also downloaded realtek from there site and no change.
I have no realtek option on my volume task bar anymore but when I have my headset it in I do.
Thank you for replying to my query I greatly appreciate it.
