Audio No sound

i had sound. Then i linked my computer to my tv with a hdmi cord, and unplugged my jack for the computer stereo. On the tv everything works. I then went back to the computer moniter, with a hdmi cord and plugged in the speaker jacks. Now unity says it cant load in the sound and i need to set my card to not be excussive. Which i set it like that. But still no sound. And yes the mute button is off in unity.

 

Have you tried to unplug everything? Then shut down everything? I mean, it works sometimes ahha
