HDA nVidia sound problem

hi, i’m using 11.0 and have problems with sound card HDA nVidia with ALC662 Analog, very often when i play music in any player the sound gets screwed-up - it starts to cackel or sometimes it rumbles. i tried using different mixers (ALSA, OSS, ESD and the PulseAudio doesn’t work at all) but it’s still like that… any help?

I don’t know how much you have tried, so it is difficult to know where to start.
Did you try any model options in your /etc/modprobe.d/sound file? Are you using KDE or Gnome desktop? What version of alsa are you using?
