that 9468 driver is a
UAD/DCH driver, not a
standard/unified/legacy HDA (non-UAD) driver that comes with the old Realtek HD Audio Manager app, rseiler. {realtek hd audio manager uses either the RAVCpl64.exe or RtkNGUI64.exe file; those don't exist for that version}
need
Realtek Audio Console (aka Realtek Audio Control uwp app from MS store) to use that 9468 UAD version.
the last HDA driver version is still 6.0.9273.1
you're welcome.
but MSI has full versions of the
6.0.9475.1,
6.0.9481.1 & recently released
6.0.9492.1 Realtek UAD driver versions from their web site.
download & install any one of those driver versions from the MSI web site, Michel86.
btw, there are at least 2 versions of "MSI Crosshair 15" laptops; one with 11th gen Intel & the other w/ 12th gen Intel cpus (ex.
B12U). the recently released
Crosshair 15 C12V models have a 6.0.9481.1 driver listed for win11 but the 9481 driver can also work for other Crosshair 15 models as well (not limited to just the 12th gen intel cpus - might also work with ones with 11th gen Intel cpus too) and on win10.
