Windows 10: "Conexant High Definition Smart Audio221" and "Intel(R) High Definition Audio HDMI"

Windows 10 has problems with two devices of my Fujitsu Si2636:

• Build in Sound Codec: "Conexant High Definition Smart Audio221" HDAUDIO\FUNC_01&VEN_14F1&DEV_5051&SUBSYS_1734111F
  (shows yellow ! icon in the device manager)
• HDMI Port: "High Definition Audio" HDAUDIO\FUNC_01&VEN_1095&DEV_1392&SUBSYS_FFFFFFFF (no yellow ! icon, but sound over HDMI does not work)

The solution is to install Windows Vista drivers from the Fujitsu Download page:

Conexant High Definition Smart Audio221 4.31.0.50 (20.09.2007)
32 Bit: https://support.ts.fujitsu.com/IndexDownload.asp?SoftwareGuid=98887CE1-7DB6-4225-B8FE-F089E5ED2CD4
64 Bit: https://support.ts.fujitsu.com/IndexDownload.asp?SoftwareGuid=099B286C-70E8-4C49-A74E-3ACAEFFEDDC4

after the installation of the "Conexant High Definition Smart Audio221" the "High Definition Audio" device shows a yellow ! icon, so you have to download following driver:

Mobile Intel (R) 945 / 965 Express Chipset family 7.14.10.1283 (03.07.2007)
32 Bit: https://support.ts.fujitsu.com/IndexDownload.asp?SoftwareGuid=1C02A242-8E93-4611-9D34-8700FD574AB8
64 Bit: https://support.ts.fujitsu.com/IndexDownload.asp?SoftwareGuid=564E1DDF-2983-4D1A-A6C8-C5490281ABAD

You can find the driver for the "High Definition Audio" device in the ZIP file under the path VGA\HDMI. The name of the right driver is "Intel(R) High Definition Audio HDMI".

Have fun!
