I am beyond frustrated, i usually can fix any software issue through troubleshooting and i just cant figure this out. I moved, didnt change anything in my set up and im assuming its just my headphones (with built in mic) malfunctioning. I went and bought just a desktop mic and plugged it in the inbound port and still the PC is not recognizing an inbound unit. I have 2 "corrupted" drivers in my device manager. 1. BT mini-receiver 2. SM Bus Controller I have tried searching for drivers online and even on driver disks that i have and nothing shows up. i do not know what these devices are and have tried searching forum after forum. ive tried uninstalling and reinstalling my audio drivers and nothing changes. When i right click volume and go to recording devices there is nothing there to choose. This has to be a driver issue, but ive not a clue where to look. I would be gracious for any assistance!
