I'm having audio problems after upgrading to Win 10 64 bit.
Dell Latitude E5520 IDT 92HDxxx HD Audio
Hardware IDs:
HDAUDIO\FUNC_01&VEN_111D&DEV_76E7&SUBSYS_1028049A&REV_1001
HDAUDIO\FUNC_01&VEN_111D&DEV_76E7&SUBSYS_1028049A
1) If I use the built-in Win 10 driver ("High Definition Audio Device") I can hear speakers/headphone, and switching between speakers and headphones works fine but my laptop microphone does not work ("Not plugged in").
2) If I use the latest driver from Dell (IDT 92HDxxx HD Audio Driver) I can initially hear through speakers but as soon as I plug in headphones I can't switch back to speakers (i.e. switching between speakers and headphones does not work) and my laptop microphone does work.
I would be happy to provide more info and to assist in debugging.
In a Microsoft Community Forum I received the following reply from Rob Brown - Microsoft MVP:

Hi,
AS OEM Dell is responsible for the proper operation of both the hardware
and Windows. Check with Dell Support, their on-line documentation and
drivers, and ask in their forums about any known issues. Be sure you are
running the latest BIOS, chipset, and major drivers.
Hope this helps.

I understand that the Latitude E5520 does not appear on the Dell "Computers Tested for Upgrade to Windows 10" list... nonetheless I've been hoping that maybe Dell might find it in the goodness of their hearts to come up with an updated IDT 92HDxxx driver... pretty please?
Thanks,
John D.
