Very similar to my desktop -- I have *two* capture settings, but I |
43 |
suppose that's because the card has two microphone inputs (front and |
44 |
rear) along with line in, and they probably wanted to allow capture from |
45 |
more than one source at the same time. So, other than another capture |
46 |
option and an option to pick the source, it seems to be the same. |
47 |
|
48 |
I'll see if I can get an older PCI card to try this with, and see if it |
49 |
gives me the capture option I want. |
