Hi,Hi,
try going into your device manager.
Find the audio device and roll back the driver.
Post back if it doesn't work.
This might make things easier. Download this app and post a screenshot of your system details:any other option sir?
Did you use Windows to downgrade from within Windows during the 30 days of using Windows 10? Or did you do a "system restore" type install for Windows 7 with original OEM type restore media that might have come with your PC? If you reverted back to Windows 7 within 30 days you must not delete the Windows old folder despite what a lot of tech websites will tell you and there is a reason for that. It could be as simple as you need to reinstall your sound drivers properly
It's important to post here what the brand/make/model of your PC is, and also "how" you downgraded to Windows 7 from Windows 10. Before you go updating any specific driver types it's best to know exactly what we're dealing with here.
So before you go installing chipset or any other type drivers lets get this information first.
Self Built or pre-built OEM-Type PB?
Make and/or model number or Pre-built
If not Pre-Built motherboard/processor type-model/video solution
Here is a good format for listing basic specifications
---------------------------------------------
Here is an example of an OEM-Pre-Built PC
Dell XPS 8700
I5 4460 CPU
16GB DDR3 1600
NVidia GTX 745
Dell 460W PSU
Here is an example of a custom built PC
Asus M5X99X EVO
AMD FX 8320 CPU
HD 7970
8 GB DDR3 1866
650W Corsair PSU
Here is a free tool that will give you the specifications that you can post in forums.

HiTry now. Direct DL link the actual link would not work.
OH WAIT!!... BioSTAR FIX MY PROBLEM THANK YOU!!!!!!If you actually did downgrade from windows 10 to windows 7 then Kemical asked you to run dxiag to test if your sound hardware is actually physically working within the OS itself. There are sound drivers of course listed in the Biostar site for your motherboard for Windows 7.
As far is the board being able to work with Windows 10 it should be ok, but may offer flaky functionality unless a clean install was done, and it would primarily be using default windows drivers. I have known many with Intel H61 boards that upgraded to Windows 10 just fine though it can vary by brand and model or the bios itself. Most H61's are ok with windows 10 from what I have seen.
