Thanks for responding. Your reply suggests the reason why Dell refuses to discuss the problem with me. I thought it was just because I was in a little country like New Zealand and did not count. I hope the auto manufacturers don't take the same stance. Obviously you have the same problems as me so here is a little info to help you use the card for SDR.
There is a driver available from Dell which sort of works.
The piece of software called "AudioAnalyserV1.9 will enable you to switch back and forth between mono and stereo until the card catches the right phase and works ok.
This software is invaluable to anyone experimenting with SDR as you can observe the phase of the incomming signals and check amplitude and phase settings. It is a must have for SDR experiments and free too.
Good luck with your card and I can assure you after my experience with Dell I won't buy or recommend their products.
