Lost all sound on Flash after Firefox updated (or shortly thereafter)

Lost all sound on Flash after Firefox updated (or shortly thereafter)
In other words Youtube and the like are silent (which is a kind of a blessing, really).

10.04LTS 32bit
Firefox 3.6.8 - (for Ubuntu - Canonical 1.0)
Flash 1.0.10 (tried r&r already)
External USB sound card, desktop system

Sound works great everywhere else, including mp3's on web through Firefox. I searched the forum, of course, but didn't find anything that seemed relevant or up-to-date.
I'm no hacker, and am apt to get lost, so does anyone with a bit of patience have a clue how i can fix this?

Thanks for any help..

Here is your clue.
Install the PulseAudio Volume Control utility (using the Software Centre), it's a nice application, you may need to use it again.

Put a youtube video playing in Firefox, then run the volume control utility and in the Applications tab you should be able to see its audio stream. Just select your USB card from the list to set it as the default output device for Flash audio streams.

Excellent! Worked perfectly. Thanks very much.
