I am just today experience an issue where the volume is reset 100% for each ad. Ads play, I turn volume down to 8%, I have the tab still on display (though I have focus on a separate window), and when the 1st ad ends, the 2nd ad is as loud as 100% even though the slider remains at 8%. Click to reset it to 8%, then 3rd ad plays at 100%.
I noticed during the olympics that they would hide the in-page volume controls during commercials. I hadn't seen that before. Fortunately it's still possible to mute via the tab control.
Not sure if this applies, but might be worth consideration
