Hi,
My desktop has a set of 3 audio connectors at the back, just where they're really convenient to get to. I use the line-in to record stuff off the radio from time to time and dont want to remove it, but I have some stuff I want to do which involves injecting a different signal into the line-in. I have found a PCI sound-card, so I could shove this in and have a second line-in connection, but how do I tell the compiuter which input I want to monitor at any time?

Bruce,
assuming that your op-sys and hardware will allow for a second sound card (and depending on the sound card they may share the same IRQ's etc so you can't), select Control Panel, then Sounds and Audio Devices, then the Audio tab.
You can specify which devices to use for sound recording and playback from the drop-down lists.

However, if you are just need this "dual input" feature from time to time, it would probably be cheaper just to add a toggle switch connected to a 3.5mm stereo jack and a couple of line sockets, or build a very simple mixer. With the mixer, you could share the line-in with 2 or more audio sources as needed.

Hello Joe,
I wrote a reply to this post this morning but it seems to have dissappeared without trace. Computers, huh! They'll never catch on.
