I recently bought a new computer [Windows XP] with the intention of using SONAR for editing/recording midis and Protools for audio recording. Initially after downloading an ASIO Driver from the Digidesign site I got SONAR working using the on board sound card. DVDs and CDs also worked as well. The mbox looked great but did nothing. Then under instruction from the music store, I disabled the on board sound card. This resulted in having no sound whatsoever. I was then advised to download WaveDriver 5.3.3. Following the instructions I removed the ASIO Driver and then tried unsucessfully [about 6 times] to install the wavedriver. Everything stopped after getting to the point where you are to select "Sound, video, game controllers". I now have no sound at all and am wondering what next?
