I'm in need of some cash and am considering selling my Audigy. My previoius MSI board used the AC'97 onboard audio and it was crap. Especially using voice over MSN or CS. How does the CMI audio compare? I'm assuming it is H/W based as opposed to the S/W based AC'97. Anyone use the onboard audio on the Soyo Dragon boards???

Duh ... onboard sound, using the AC97 bus to connect a codec to a chipset integrated sound engine, is NOT inherently software driven. And PCI sound chips aren't inherently hardware DSP driven either. There are just as many brainless PCI sound cards as there are intelligent chipset integrated solutions.

That said, CMI8738 is about midway between the two extremes. Best budget choice.

Even CMI8738 6-ch based card costs about $20 after shipping.
You won't get much cash by selling Audigy and buying CMI8738 based card.

Forget about it. Try to cut corner at somewhere to get that $40 (assume you could see the Audigy for $60).

The CMI is onboard my mobo ;)

You said it's AC97 software 2-ch, I thought it's just the VIA southbridge + codec.
Then keep your Audigy, how much can you sell it now?
Today a new Audigy oem is just $60 shipped.
Try to eat $2.99 meal instead of $3.99 meal for 60 days, you can save $60 soon.

Heck, I found new CMI8738 cards at a computer show for $9 each. I bought one for my mom's PC, and it works just fine.

AC97 audio - it sucks (in my experience anyway). Plain and simple. It might be adequate for making Windows go BUNK when something's wrong, but it's not good for much else. In my experience, AC97 audio had trouble playing MP3's for me. Not good.
The CMI8738 chip is more hardware based, but it does have high CPU usage as far as soundcards go. Keep in mind, that's "high" in a relative sense - compared to other soundcards.
I've used the Shuttle AK35GTR, which is pretty similar to the one Dragon board from Soyo, don't remember which. I almost bought a Soyo KT266A board though. There were problems with static in games, but that seems to have been resolved with BIOS and driver updates.

Easy way to test if the onboard is ok: uninstall the Audigy, enable the Cmedia chip in BIOS, install drivers from Cmedia's site, then install the drivers from Windowsupdate, and give it a try. Cmedia is weird about driver updates - v639 is on their site, but Windowsupdate has 641. They seem to be slow to update their Download page for some reason.
You might want to check for a new motherboard BIOS file too if you experience static in games.
I think that the CMI8738 is one of the better budget sound solutions out there, though if you are looking for a motherboard with onboard stuff, the nForce's sound is supposed to be very good too.

Isn't it amazing how right after you explained something, someone else comes up and repeats exactly the same wrong stuff all over?

Again, such a generic opinion is just plain bullshit. Hint: Audigy uses AC97. Questions?

I think that is pretty much the type of answer I was looking for.

Not sure why I asked for a comparison, as I don't have the mobo with AC'97 anymore :confused:

Basically, I currently use an audigy, but have the Soyo Plat P4 mobo with the CMI onboard. Considering selling the Audigy for some cash to feed my new Gamecube with some games.

So will you play games mainly on consoles than pc?
I used to spend a lot on top sound cards like SB16ASP, Gravis Ultrasound.
Now I only use ICH4, good enough for casual pc gaming. Haven't bought any sound card after SB Live.
