Sound Blaster Z Dolby Digital Live weird sound echo feedback

[ankido]

I've been using my card fine. I decided to go into the Sound Blaster software and like an idiot I accidentally hit Dolby Digital Live and the sound cut off. Obviously because it's not set up for that. I went back to No Encoder and now my sound keeps giving back a feedback like echo sound and it won't go away. I uninstalled the drivers and that didn't work. I restarted the computer numerous times and that didn't work. I have no idea what to do. I remember this happened last time but I don't know how I fixed it. I do however know it took me days before I figured it out. I'm so tired of Creative Products, they never work right.

Anyone know how to go back to No Encoder and make the sound normal again?

I'm so stupid. "What U Hear" was on 100%. Lower it 0 and that fixed the problem.
