Hopefully to help anyone else with laptop & win 11 24h2, ive tried installing (per instructions) countless times to no avail. Every time the software would always say something to the effect of "device not present", device meaning authentic sound blaster device or dts, etc. I have a realtek ALC256, clevo laptop, i9 13900hx etc. upon deleting the file
"intcsdwbus.inf", strangely everything works. I am going to post a screenshot of my realtek HDA test utility. Can anyone tell me anything about what this means? IE "Has RTKHDAUD.DAT" in red. the other one is in green. the check boxes next to them. what does all this mean?
Has DAT file just means the DAT file exists in c:\windows\system32\drivers
there is never a config DAT that i have ever seen
The DAT file stores the options and it read by the driver to see what things should be enabled / present / visible etc
If you got ABCXXX chip and you implement it in say a laptop, with only a unified audio jack
and then implement it in a desktop with 8 analog outputs on the rear panel plus a front panel
you dont release different drivers exactly
you release same driver but different dat, and disable or hide features the laptop cannot actually provide
like the 8 analog outputs.
Simplified example
PS
It you modify the DAT file via the utility, back up said DAT file incase you ever need to reinstall
that way once you reload drivers, you swap the DAT file and reboot and your settings are back.
