Chosen Solution
I have an asus sabertooth 990fx r2.0 and it is about a year old. My onboard audio has not been working for the past 4 months. I have to use a USB headset for any of the audio, the analog jacks dont work. I have tried everything, reinstalling drivers, reinstalling the OS (win10), Nothing works. and I have tried all the advice I could find online with no success. Now here is where it gets strange, The back panel and front panel audio dont work, and if I plug in a working internal sound card, it wont work. I tried 2 different internal sound cards and nothing. It seems like any analog jacks I plug in just dont work. In the audio manager part of windows 10 under control panel, it shows 2 audio devices. It shows doth that are digital out, no analog options are available. I an fairly experienced with all this and I know about installing and uninstalling drivers. and I have also tried every option in the audio manager system.
Try a bluetooth USB dongle. Bluetooth’s audio protocol and stack are independent of anything built into the motherboard.
i am assuming you are running bios version 2901? I and hundreds of others have had this issue. you need to do a bios roll back. prepare a usb drive for the bios repair button on the back. if you use the software version it wont let you roll back so you have to act like it was a catastrophic failure and use the bios boot button. 2901 has some messed up code in it that conflicts with the audio system. in my machine i lost optical first then a few weeks later the audio ports so i didnt realize it was a bios issue. the way it happens almost makes me suspect it was a planned obsolescance failure. Apple does this all the time by slowing the machine down with each update until its no longer usable but if you go to an earlier OS it runs super fast and smooth.
