The standard way to install sound cards is to find out what kernel module supports your card. Then "insmod" it. Redhat's hardware detection stuff should do that for you though, so you sound card may not be supported by default....
Hehe, your in luck. The alsa-project supports your hardware. You can find directions on howto install it
here.
Those directions are specific for you sound card, be sure to visit the main site for downloading the source code and all that happy stuff.
Of course, installing alsa drivers are a bit of a pain. The directions are very consise, though, and if you make sure to follow them pretty much exactly you'll be ok. It may involve recompling a new kernel and that is scary to some people, but once you learn howto do it (be sure to make a bootdisk before...) it's not a big deal.
Those Alsa folks are audio freaks. Their goal in life is high fidelity sound and try to provide professional-level audio support for Linux. They made my little cheesy onboard audio sound like a million bucks. I would love to see what they can do for your system..... If you are a audio guy and love to tweak your sound for best performance you will be in heaven. (I even had dual sound cards for a while!, not much point though, hehe)
Good luck.
Be sure to come back and tell me how it goes. Remember I went through the trouble of finding you a link. I am looking for a new sound card and would like to see what sort of results you get!
😉
PS. their probably is a easier way to do it, try going to Redhat.com and see if they support you card, however you probably would be limiting your sound card's poteintial.
