But still i do have not sound (speakers,jack,hdmi), FV: MrChromebox 4.21.1 i installed all drivers from your site for my blipper but i have missing a 3 devices on device manager : ACPI\VEN_INTC&DEV_1026
Anyone have any solution for this ? Thanks

Coolstar’s Thunderbolt drivers will fix this (you dont have buy a license as i don’t think this model is TB4)

**Extract with 7zip -and search folder automatically from Device Manager

search for: gNoDriver.inf
*need to manually point to the PRP001 driver tho (it wont auto install)
