Body
WMI does give some information about sound cards. What I haven't been able to find out yet is whether its giving enough. Using "<a href="http://www.microsoft.com/downloads/details.aspx?familyid=2cc30a64-ea15-4661-8da4-55bbc145c30e&displaylang=en" rel="nofollow noreferrer">WMI Code Creator</a>" the following script lists everything that the <a href="http://msdn.microsoft.com/en-us/library/aa394463.aspx" rel="nofollow noreferrer">Win32_SoundDevice</a> object stores: <pre><code>strComputer = "."

It's a tough question.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
