I'm using an ASROCK H61M-HVS with VIA HD onboard audio. Noticed that the default drivers windows installs for it are completely fucked. Enhancements don't work at all, and it keeps defaulting to headphones (front jack) even when you only have speakers plugged in.
To fix;
Right click your start button, click system, and then go to advanced system settings
Go to hardware tab and go to device installation settings
Click no, then click Never install device software, then click okay.
Open Device Manager
Go under the sound field, select VIA HD Audio, and uninstall the driver, then restart your computer.
Go to https://support.microsoft.com/en-us/kb/3073930 - download the .diagcab file. (Windows 10 has removed the ability to blacklist updates without using this file)
Go through the steps and choose to ignore the VIA HD Audio update that is queued up.
Congratulations, your sound drivers now work properly.
