Unable to play Soundcloud audio streams on Ubuntu 11.10 64bit

[sdavmor]

When I connect to my Soundcloud site (or any Soundcloud site) I get
the following message:

"Hey, it seems your browser can't play SoundCloud audio streams. If
you can, please take a moment to upgrade your browser or Flash Player
plugin. Thanks for your understanding!"

I am running Ubuntu 11.10 64bit. Up to date on patches, and up to date
on the Flash Player plugin (I checked the rev level at the Flash site
and it's fine).

Anyone else getting this? Anyone have a solution? I want to change
some of the tracks we offer there in readiness for the new Systems
Theory album. Not being able to hear anything is a big hole in the road!

TIA.
