I have installed RC1 on my notebook and everything seems to be running fine except for the sound. i've tried to use external speakers but they don't seem to work either. I've un-installed/re-installed the driver.. No Joy. I've even gone so far as to re-install RC1. So, is there anyone out here that has had a similar situation and has a solution?? thanks Oh.. I am running a Gateway 7320.. thought that might be helpful.
