VirtualBox OpenSolaris guest

[Harald Weis]

Does anybody know how to correct the audio driver problem of the
opensolaris guest?
The internet advice to run
pfexec update_drv -a -i '"pci8086,2415"' audio810

is better than nothing, but the audio quality is absolutely miserable.
It is clearly not the required audio driver.
Therefore the flashplayer, i.e. the ***only reason*** why I've installed
the opensolaris guest (following the advice of C. P. Ghost <cpghost at cordula.ws>
on the questions list), is useless:-( 

The other point is that the installation of  additional
repositories (needed for mplayer for example, I dislike totem) does not work
either.

My hope to find an interim solution for the flashplayer nightmare
(while waiting for gnash) can be measured by the amount of hours
I've spent to get flash - easily and long-term-wise -  playing  on FreeBSD,
Ubuntu, PCBSD...

I guess that FreeBSD will never be supported by Adobe.

Thanks in advance for any help.
