Everything different from Analog Stereo Duplex and Analog Stereo Output option in Pulseaudio settings affects my system too.
High-pitched and distorted sound effects coming from speakers or headphones, especially audible when I click on the top panel button (eg. console launcher icon, firefox launcher icon, etc. associated sound effects).

My config:
ALC888 (snd_hda_intel) and Karmic 64 bit with official repository kernel.
