Good folks of Techspot. I have a Realtek HD Soundcard on an Republic of Gamers Asus motherboard a maximus V I think. Windows 7. I am using OBS Multiplatform to capture and record my 'videos'. Whenever I talk there is a hiss in the background. Which just sounds awful. I have spent 2 days in google-dom...trying everything : I have unplugged and turned off speakers with both Mic and Speaker jacks going into the back. I have turned off all wireless emitters for a 5km radius (much to neighbours chagrin) I found some advice telling me in my Recording Devices Tab (or via the HD Realtek Manager) to Disable All Sound Effects, and specifically to check "Acoustic Echo Cancellation" in the enhancements tab. But....there is no option in the enhancements tab. Just DC Offset cancellation. I have checked the other THREE computers in the house, they all have this option. So I assume its the Realtek drivers for ASUS/ROG ? that is ommiting these options. What can I do (bar buying a new PC) Oh and I have uninstalled and re-installed the drives (tried it with just windows drivers) ... but no Enhancements tabs at all. My Witts end was passed about 4 hours ago. Pleeeaaaaaseee if you know an option help. I am even tempted to go to Windows 10 !!
