hissing/static sound from both pulseaudio and ALSA

I hear a hissing sound whenever the volume is not muted.  At first I thought it was a pulseaudio problem but I still hear it when not using pulseaudio

Have you tried muting your microphone?
Is this an analog sound system or is digital (like HDMI) ?

It's analog and the microphone is muted.

Have you tried to lower the gain in alsamixer for your devices?  If the gain is too high you might be getting noise off the circuits.

It's in the negatives. And when I lower it even more the static can be heard more easily over any sound

I think I found the problem but the solution is on a ubuntu ppa.  the ppa is https://launchpad.net/~ubuntu-audio-dev … alsa-daily and the package is oem-audio-hda-daily-dkms I think that this is the solution as a user on the ubuntu forums were having the same issue with a similar motherboard  http://ubuntuforums.org/showthread.php?t=2234198 .  Can anyone help me?
