Ok. I had the sound glitch again while on one of the boats. It lasts for about 3 to 5 seconds and then goes back to normal.

Nothing to see in log file...

Then it's obviously an issue that's not showing up in the log file for whatever reason. I haven't had the sound issue in 1.8.9 or with any other applications so I know it's not hardware related. Also, I've only noticed it happening in the ender world with the latest snapshot.

I think that's a soundtrack for The End, doesn't it is?

It sounds like it could be coming from the music rather than one of the sound effects. I don't hear when I fight the ender dragon, it's only when I enter the end city.

This issue duplicates MC-86790?

Oh, yes. It's the Music.

Ha ha, oops. Mystery solved.
