Well, not completely. I have the same problem here (Ubuntu 6.06 host,
different guests). When I start VBox with alsa plugin, I can no longer
use anything with sound. When flash or something starts in Firefox,
the whole browser deadlocks and I need to kill it. Even though,
Firefox is configured to use alsa output and it generally works.

One note, though. I have an alsa client running all the time (one of
those noce Amilo Si 1520 bugs... needs a bit cpu load otherwise it emits
a high pitched noise... another story...). The client is more or less
aoss mpg123 silence.mp3... This one is not affected by running vbox.
But doesn't that mean, that VBox will never have an exclusive lock on
the soundcard?

Regards, Frank, first post here.
