Audio bug (Gotten worse since Tahoe 26)
Since the macOS 26 (Tahoe) the screensaver's preview on the settings plays the audio of the videos all in the same time, same with the screensaver mode, one video plays but the audio of all the videos saved plays at the same time or even twice on different timings, creating so much chaos that the video played cannot be heard (and it's painful as a headphone user)
Ok sorry but I'm not quite sure what you are saying here exactly ?
According to your screenshots, you are not using Aerial.
1st one you are using a DVD one, second one you are using the built in macOS clone of Aerial with a wallpaper set as the screensaver. Where did you add videos ?
In my case I cant even use the Aerial, cuz I see Wallpapers and there is no Aerial in macOS Tahoe. Not even when Im entering to screensavers
