[linux-audio-user] 2 audio cards with Red Hat 9.0?

Is there a way for Red Hat 9.0 to switch between two different sound cards? I've got an ASUS A7N8X motherboard that has on-board audio. It's a Realtek ALC650 6CH with built-in HP amplifier. This is what Red Hat identifies now. I need it for DVD movies and audio CD since it can be connected to my CD-R/DVD-ROM drive. But for recording, I have an Audiofile 2496 PCI sound card. It's in the machine now, but Red Hat does not recoginize it. There doesn't seem to be any way for the CD-R/DVD-ROM drive to connect to the Audiofile 2496 PCI sound card. Is there a way for Red Hat 9.0 to recognize both at the same time, or to switch between them?
