[Asus P6X58-E PRO, Realtek ALC889, Green Line Out, Rear] Background noise or low volume

[Ekangas81]

This occurs on the Ubuntu with wubi installer. I have installed previous versions of linux on the same hardware which didn't have this issue. Windows 7 doesn't have this issue.

Lots of background noise whenever turning up the volume.

I tried this on Ubuntu 13.04 also, no luck.
I got this same problem after trying out multiple distros on the same PC. I don't get this problem in Windows 7 Ultimate at all.

I followed this article to uninstall PulseAudio
http://www.hecticgeek.com/2012/01/how-to-remove-pulseaudio-use-alsa-ubuntu-linux/
still no help.

I verified that my Maaster and PCM volumes are not zero, and tried various different settings.

it is strange that dB are 0.20 in amixer since dB range of softvol is -51 to 0

Simple mixer control 'PCM',0
