win7 sound

[flollar]

Problem: audio services

cannot be started in Win7Pro​

History

No sound on Win7 started after dual boot adding Win10 by new partition for Win10. Both system worked OK except no sound on win7 boot, sound Ok with win10 boot.



Win 10 OS removed by formatting the partition with win10. Now win7 boots OK but no sound.

Current symptoms



When Sound is selected from control panel the following pop up is seen:

When “yes” is selected, pop up tab says “no audio devices installed”



Device manager for sound pop up; “no sound devices installed.

In device manager for “video and game controller”. both devices;

High definition audio device and Intel display device are working properly and. latest drivers installed.

Services (local):



Win audio cannot be started…error 1068

Dependences:

Multimedia class scheduler cannot be started; error 126 can’t find module

RPC: started

DCOM: started

RPC endpoint mapper: started

Win audio endpoint builder: ; error 126 can’t find module

Plug& Play: started



Trouble shooting tried without any fix:

SFC scannow

Windows memory diagnostic check

Windows repair my computer with install DVD

Windows module installer: stopped/restarted + reboot

System file checker





I assume the problem is somewhere in the registry. I am comfortable with changing registry values, but don’t know where to start.



Thank you for any help,

Frank

It sounds like you checked the driver & the hardware and the dependent services.

I don't have an answer myself but it mentions over on another Win 7 forum that to fix " Win audio endpoint builder; error 126 can’t find module" you may need to enable the Power service:
"Windows Audio Endpoint Builder" service will not start - Page 2 - Windows 10 Forums (sevenforums.com)

So, maybe try that or ask on their old thread?
