Yes you said it right I am also getting the same message as you are getting. I have also recently upgraded to the Nero 10 and the problem started. I have searched it on the internet but have not found out the suitable solution for it. I have never received such problems with the Nero 7, 8, 9. But I am getting it in 10. So Is there anyone who can help us out. Thanks, to all who are going to reply.

I also had the same problem. I think during the release the Nero should have also given the list of setting to be done. Any how I have solved out my problem and thanks to this forum and all those who gave the solution. The problem was that I had recently switched xfi sound card to m/b sound chip.

I think that there will be hardly any different answer to this thread because to solution provided above is absolutely correct and I don’t think that there will be any other solution to it. I think we should be allowed to choose Stereomix or Wavemix. This option is not displayed in the windows 7 normally because it is normally disabled and we need to enable it manually. Sorry I don’t know how to do that.
