Everything was working great and for no reason I can figure my Auzentech soundcard resorted back to it's defaults and running Windows trouble shoot that used to find any problems just keeps running and running. I select Playback Devices and no window opens up and from the start menu, clicking on the control panel or other options brings up nothing. I have uninstalled the drivers and all of its' components. Shut down and unplugged the computer and removed the sound card from its' slot. Restarted and loaded the latest driver package, restarted and reinstalled the sound card and I get some sound but still no window for playback devices or trying troubleshoot. Any ideas or suggestions guys? I am running Windows 10 all up to date. I can't figure it out. Yesterday I watched 2 movies and the surround sound was great and all the functions worked but today I have little or no functions.
