I noticed this starting today. There is an ad (for Acura, I think) which starts playing a video with sound while the page is loading. I did not click on the ad, or roll over it. I don't mind ads, but can we agree that BigSoccer pages should not be automatically playing ads with sound so we don't need to scramble to mute our speakers if we are in a situation where our computers should be quiet? The alternative is to install an ad blocker.
I'm starting to think it's specific to my browser. I just heard it again - but the ad was not visible. The ads that I could see were for "Fuelly" but I heard the Acura ad playing in the background. I scrolled up and down and couldn't see any ads other than for Fuelly. Imma clear my browser cache and see if it happens again.
I heard an ad while using Edge with ad block. I couldn't see any ads on the page, but there was audio.
