sound perfect + flashplayer no sound
 

Hi I have a board sis with athlon 1200 video sis 630.
Sound sis sound acceletator on board (at least linux redhat 7.2 and 8.0 say it is that sound card).
The system works fine with realplayer and xmms but when it comes to flashplayer inside pages sound doesn't work.

I tried installing redhat 7.2 and 8.0 but the problem remains.
Can anyone give me a hint

thanks
