You can find the drivers here "MoKiChU" posts updated drivers all time. Realtek Audio Drivers (UAD - ASUS ROG SS3-DTS MB) :
Would it be possible for someone from ASUS to comment
Be aware that this is primarily a community forum. There are a few ASUS people that visit here but they don't answer every thread. Also I don't believe any of them work on the actual drivers so they might not know the answer.
Hopefully there will be new updates for Win11 drivers soon so you won't have to worry about using that old one.
On a side note, Mokichu doesn't write or edit the actual drivers, just organizes and repackages them. So while he's not affiliated with ASUS I don't believe any of his releases should ever harm your system.
I downloaded and installed the (win 10) 9244 drivers on my Dark Hero a couple weeks back. Since then I've had multiple random hard lock ups in windows while gaming. Complete hard locks - need to reboot the PC. In every case when it locks up there is a repeating, screeching audio sound playing non-stop. My guess would be that there is something wrong with these drivers so they've been pulled. I was coming here to see if there was any discussion about them before I rolled back to the previous drivers.
Repeating the info I posted on the other thread about the Dark Hero not having the same exact audio codec as the CX-8 Hero. Asus US site for these boards says the Dark Hero has ROG Supreme FX7.1 Surround Sound High Definition Audio CODEC and the Crosshair VIII Hero has ROG SupremeFX8-Channel High Definition Audio CODEC with DTS and ESS. I don' know exactly what the difference is between these 2 codecs but the Hero seems to have the better one, which is surprising. I don't know if that means they should have different drivers.
