Was watching a 30 minutes video. 15 minutes into it an ad got displayed for 15s. When normal program resumed, A/V sync was off by about 3s. I've reproduced it twice ; unfortunately, getting the ad mid-stream appears random.
Summary: After an ad is displayed in the middle of a video, A/V sync is broken. → After an ad is displayed in the middle of a YouTube video, A/V sync is broken.
I believe this is something Maja reported alread; so likely a duplicate of another bug
I haven't seen it myself, but Syd described something similar while working on EME tests in a hotel room with terrible wifi.

I was testing our automated video tests. Basically, I saw three behaviors when there was a network stall: - The video started where it left off. - The video started, but audio was not in sync. - The audio kept playing, and the video played real fast until it caught up. I don't have a good sample as to how often each event happened.
