You have an ASUS ROG SS3 notebook, so :
You need Realtek Audio Drivers (UAD - ASUS ROG SS3 NB/DT) from the first post of this thread.
Follow scrupulously your CLEANUP process then your INSTALL process, for the next drivers packages that I would release, you will can directly follow your UPDATE process.
Hi. Actually mine is a Rog Strix Scar 2, not 3. Not sure if that driver would work aswell in my device
I know perfectly well the notebook you have (ROG Strix Scar II - GL504GW), otherwise I will not have told you what to install/do.
Note (this is probably what made you doubt) : SS3 does not mean Strix Scar III, but means Sonic Studio III.
May I have an audio or video record of the issue?
