I'm hacking together a modified sound solution inside a thin client and would like to build a small audio mixer on a proto board to combine the sound between two different audio connectors. The primary reason for this is that the add-on PCI card will be using VXD drivers, and the onboard will be WDM. The advantage of this is that I can combine the legacy compatibility of the VXD drivers with the luxury of the WDM MIDI mapper, which includes options such as Microsoft's GS and Yamaha's XG software synthesizers.
I will be removing the onboard connector and adding solderable 3.5" audio jacks. I don't know much about combining audio signals, but it doesn't sound right to me that I would just solder the signals from the two cards onto the same connector. This would effectively be connecting the amplified output of one card to another, and I don't think that's a good idea.
What would I need to build a small mixer for my intended purpose? It would mix the audio outputs, which I think are amplified and not line-out, together. I'm not even sure if it's line-out or speaker out. Is there an easy way to tell?
