HDA Intel vs. Realtek ALC888 audio on one machine?

Looks like I'm a regular newbie around here. Eye

There's one bit I don't understand since I built this new computer. It's almost as if the motherboard has *two* audio systems on it. The volume control applet in GNOME let's me change between two audio devices:

- HDA Intel (alsa mixer)
- Realtek ALC888 (OSS mixer)

So is this actually the same system only differently interpreted and called by OSS and ALSA or is it maybe that this system has two modes of operation or do I actually have two optional audio systems (which really seems unlikely). I'm just a bit confused about it.

I'm interested in this also because I still didn't resolve the problem of fuzzy sound in certain programs (including games) which makes sound less than pleasant.

Any thoughts?

How's it plugged in?

Do you ever plug the speakers into different places? If you don't, perhaps the two labels are actually the same device, but both Intel and Realtek sell it.

Well, I can switch back and

Well, I can switch back and forth between them without plugging it anywhere else. There are 6 audio ports and I can change between them, but this doesn't really affect anything, but maybe the current volumes in the mixer. Not much to do with sound distortions.

It could be the same device sold by both of them as you say.
