I made several tests; in the beginning, of course, there was the original Sony driver; I check for some updating on Sony Site and also on RealTek site but, after the installation, in both case the situation do not changed. At the moment there is the last version of the Sony driver.
I call also the Sony Italy customer support and the answer was that probably there is a system block to avoid people copy (in wav) the cd !!!
I can't beleive that this is true because I should be informed in advance about this approach.
As you can see in the attached image, in the recording panel there is only the microphone icon and it has been configured to show the hidden devices.
