Due to revenues going down big time for the last 6 months, I recently enabled the non-text ads in order to test things out. I did it about 2 weeks ago.
You probably saw that message about non-text ads in a notice that used to be displayed when ad-block was detected. I removed it, as it didn't make any difference.
Are you really getting pop-ups out of those ads? As for the sound, I disabled all ads containing actual videos or sound. I'm surprised, as this isn't suppose to happen. I didn't experience that yet with the ads running on here.
