Sound card on Linux Red Hat 7.3

[zz2lol]

My computer has 2 sound cards, one onboard and other AWE64. The Red Hat 7.3 detected both cards, but the sound comes from onboard card. How can I setup the Linux to disable the onboard sound card and enable the AWE64 sound card?

Isn't there a jumper on the motherboard or BIOS option to disable the onboard sound?

Disregard my previous post.
