RealTek ALC888DD Static?

[Henry Rayker]

I just built a new system and have an issue with the onboard sound. The mobo was part of the Shuttle Prima XPC SN78SH7 barebones setup. I just installed Fedora 9 this evening. (32bit version, as my wireless wouldn't work at all with the 64bit version).

The soundcard is apparently a RealTek ALC888DD.

The output of:
cat /proc/asound/card0/codec#0 | grep Codec
is:
Codec: Realtek ALC888

So I assume it is using the proper codec. However, the audio out of the speakers (and headphones/anything else) is interrupted, quite often, with a static kind of sound. It sounds a lot like what happens when you drive a set of laptop speakers too high...except this occurs at any volume (even whisper-quiet).

I would love to find a resolution to this issue, but at the moment, I'm at a loss.

Any help would be vastly appreciated. If there is any additional information needed, let me know and I will try to provide it as quickly as possible.

I updated to the lasted drivers (from RealTek's webpage) and, to no avail. I did run into some errors in the installation (I needed the curses -devel package, alsa-tools (for alsaconf), and gcc) but after installation completed, I was left with no sound... I'm at a total loss.

Another update:

The static is really more of a crackle...not that that makes it any more less annoying.

The crackle happens less often when I disable pulseaudio, so I decide to just ditch it entirely....to no avail. The crackle is still present, just not as often. It is still WAY too frequent to consider listenable...

Update:

I found some complaints about a crackling sound being caused by activity on the PCI bus...so I removed my PCI network card and still got the static/crackle.

This issue is incredibly frustrating.

Fixed! ..... Well, sort of.

I found a thread on the openSUSE forums about this issue, but it was unresolved. I tried following their advice, but in Fedora, and wound up with no sound at all. Installing alsa from source seemed like a bad idea...

I decided to install openSUSE, just to give their advice a shot in it's own environment. I would up getting it fixed by:
putting this in my /etc/modprobe.d/sound file

alias snd-card-0 snd-hda-intel
options snd-hda-intel model=auto


Then following the instructions to install a new version of alsa found here:
http://en.opensuse.org/Alsa-update

I really liked Fedora, and may check in every so often, just to see how things are going, but everything is working great in openSUSE, so I think I might dabble over there for a while.

This is my first post of any kind
I have a Biostar with nvidia 8200 chip set and ALC888S realtek sound on board experienced very
scratchy broken sound. Solved the problem by installing the development version alsa-driver-1.0.18rc3.tar.bz2. Following the directions given here {https://fcp.surfsite.org/modules/newbb/viewtopic.php?viewmode=thread&topic_id=45428&forum=10&post_id=209226.} you will need to install a compiler and kernel-devel for your kernel. Check your kernel version in terminal with uname - r and your alsa version with cat /proc/asound/version. Took me a long time to find a solution still a noob but
working at it. Hope some find this useful.
