Hi all,

hopefully someone can help, Lenovo IdeaPad 3 chrombook, installed windows 10 without problems, bought the sound drivers from coolstar, updated the drivers including Intel chipset driver, currently I have no sound windows trouble shooter recognizes that there is a driver but with a problem (no sound output device).

Under device manager I can see three items with exclamation marks:

PCI Data Aquisition and Signal processing controller.

PCI Simple communications controller.

Unknown device

Also one item under sound:

Coolstar SOF Audio (WDM)

Thank you for the help.
