Dell with no audio-in

First off, does the tuner card have an audio out jack on the rear panel? If so, all you need to do is connect a short mini-plug to mini-plug cable between the line out of the turner card to your line in jack.

If the card does not have a line out jack, you will need a custom cable. You need to connect the cable from the card to the line in jack on the Dell audio panel.

Based on my experiences with a Russian tuner card, you can get round the cable problem with a 'soft' approach.

The supplied software sometimes (as in my case) adds an additional slider control to your advanced sound configuration controls.

By additional I mean it's not tagged on to the end of the slider panel - it is a separate slider on its own, accessed through the preferences dialog for the supplied software.

You then have a choice of 'analogue' or 'digital' for the sound received from the tuner card.

My old tower with tuner card fitted, doesn't use a cable for sound but receives the sound into the system via the PCI slot from the tuner card direct.
