The audio is choppy (stuttering) on my Dell XPS 13 Developer Edition laptop and Ubuntu 13.10. Absolutely everything is updated to the latest version.

It sounds like all sounds are punctuated by short gaps of silence at about 2-3hz. It makes the game unplayable with the volume on. Oddly enough, it plays fine on all my old desktop PCs (all running the same software). It only produces this annoying effect on my laptop.

I've tried using Open JDK versions 6 and 7. I've used Oracle JRE 7. I'm launching the game via the FtB launcher and using the very latest Direwolf20 modpack installed clean each time.

Can anybody offer some advice about how I might fault-find and eventually resolve this situation?

Have you attempted Java 8? Technically only in beta, but it works great for some people.

Silly me!

I discovered the problem - my Pulse Audio sound output was set to Stereo Duplex instead of Analogue Stereo.

Correcting this fixed the problem immediately.
