After update the Pavilion 8228ea Notebook works well. I accepted all updates proposed by Windows update.
Sole problem: High Definition Audio controller mentions "controller cannot start". Manufacturer: Microsoft. Place: place 0 (internal bus high definition audio).
Driver is: Microsoft, 19/11/2010. Version 6.1.7601.17514; Numerical signature: Microsoft Windows.
Using Microsoft problem solving, I reinstalled several times the driver and restarted but this didn't help.
Could you tell me what's the problem and how to solve it ?
Many thanks for your advice.
