[7466FVG, Conexant CX20561 (Hermosa), Speaker, Internal] Underruns, dropouts or crackling sound

[Niall Murphy]

Sound on built in speakers on Thinkpad X200i crackles, goes silent, returns to normal.
Restarting pluseaudio helps for a few seconds and sometimes the "test sound" button on the sound settings dialogue also helps.

This problem re-appeared after upgrade to 12.04.
