[linux-audio-user] Freesound preview problem

I just installed Ubuntu Dapper Drake. I am trying to hear previews
browsing the Freesound web page using the bundled Firefox, but
nothing's heard. It works fine here on W2K with Mozilla.

ALSA works fine. I can download the samples and play them using aplay.

Anything else needs to be installed or set up?

Cordially, Ismael
