A friend has bought a new Dell desktop computer, and is having issues with his audio output (some latency etc.). Trying to google for a solution we want to find out what sound card/device he has. Now, his device manager lists 3 devices (see screenshot).
Question: Are the three listed items actual sound devices (card/chip), or are these items just drivers? Where can you find out (in Windows 7) the actual specs of the audo devices?
General questions: It is very unclear to me how audio controllers, drivers, and output devices (line out, etc.) are organized in Windows. There seem to be a million dialog boxes that affect audio settings. How can you know for example to which devices/driver a certain output port is connected? An explanation (or a link to such a document or page) would be appreciated as well.
