Just installed an ASUS P4PE-X m'board. With the ASUS CD version SoundMax driver and with the latest SoundMax driver download from ASUS' site, same problem. No other sound card installed, although there was on my old m'bd system using this same HDD. Uninstalled and reinstalled SoundMax. Removed and depowered all CD drives, disabled midi and game ports in BIOS, upgraded BOS to ver 1005. None of this changed a thing. SoundMax seems to install fine, but no output, just the error message. What other application could be taking the digital output? Or s this just a bogus or default error message? No replies coming in from ASUS on this. SoundMax sends you back to ASUS.
