Hey,
@Alan Finote , did you get the chance to check out if there is any folder I should delete from FileRepository?
I was browsing the filelist I sent and noticed that was a folder with the mentioned pattern (starting with "HDX...). I deleted it as instructed, reboot and reinstalled your mod driver. I set the parameters on RTK Device Tweak, even those Driver Policy ones, but no luck again. Still can't get the option to set Dolby Digital as output.
I don't know if it's relevant, but when I reinstalled the mod drivers and launched the Driver Tweak app for the firs time, there was a red sign blinking "Has RTKHDAUD.DAT".
Is there any actions I could take in order to enable 5.1 digital output on my computer? I'm almost giving up.
Thanks again!
