Hello every body,
I'm agree with you, it is a realy good audio system and I had the same problem like you.
After lot of installation and unstallation of drivers, I tried every thing which was possible. I finally manage to make it work fine. I simply brutally unpluged the power supply of the speakers when all was on. I plug it again and switch on with the telecommand and all was working fine. I turn off the computer and restart, all is going fine. Don't ask me how what happen but it works ! Maybe an internal reset.
I hope it will work for you too.
Sorry for my approximative english ;-)
Can't believe what I just read... then it worked for me too. KISS they said...
