Flash is usually a pretty straightforward installation for FF, I'm
surprised to hear of such problems.  However, if it is sound related
only, this may have less to do with "Linux" and more to do with your
"window manager" whatever that might be. 

For myself, I use the enlightenment window manager for no particular
reason other than I liked it when I started using it years ago.  That is
only relevant because of the way I fixed a similar problem.

One of the problems with the default install of some window managers is
that sound is only audible from one software app at any given time.   If
you have xmms, for example, playing some music, your sound card will be
busy doing that, and will not allow for flash audio.   Start by ensuring
that you have only one application using the sound card.

If that turns out to be your problem, you may need to add a layer in
between your app and the sound driver.   In my case, the solution was to
add the enlightened sound daemon, libesd0 and libesd-alsa0 come to mind.
This resolved my issue and since I setup that config, I no longer have
an issue with sound being blocked from one app, because another is

I really don't know about the specific sound configs for other window
managers since I don't use them often, but this concept may point you in
the right direction for your specific window manager/application.
