Probably it doesn't add any scientific value, but I was expecting sound with the video (even if it all is noise)

It probably would sound like noise.

Hurricanes are interesting to listen to, though. The banshee wails of the winds as another band comes through. The low growling/humming sound when it is otherwise quiet between bands. The wet, snapping of death coming to a tree.

Yes, if they put a microphone on a Mars rover, why not on an ocean going drone? A microphone deep in the water might be nice too (and I would be very surprised if they don't have those for applications in marine biology and military).

Here's a nice article [1] on underwater sound in extreme storms, note in the referenced paper [2] they managed to deploy a hydrophone under 10 m waves and 40 m/s winds! This type of research is largely military funded, not for its direct applications but more because sound is so fundamental to everything a navy does. There are also civilian applications for measuring waves, wind and rain, either in extreme conditions like [2] or where a surface buoy is impractical (e.g. in locations where surface buoys tend to get stolen or broken). It's definitely a case where one person's "noise" is another person's "signal". I too am a bit surprised saildrone didn't have a hydrophone on their rig, maybe they did but the sound is not so interesting for the press release.
