One more suggestion:
try running distributed-net or something else that uses 100% cpu.
I also have "bad sound" from on-board audio (hp nx9110 notebook
and some elcheap asus motherboard). Usually it is a bad or cheap
motherboard design.
If using your CPU 100% fixes or mostly diminishes your audio
distortion, you can be 100% sure that the audio part has a very
bad design (no separate voltage controllers or good power supply
filters, and no separate power supply circuit, and of course a
good deal of crosstalk between analog lines and "digital" lines).
