Affected hardware here: Lenovo Thinkpad T430s. Suppose the Lenovo Thinkpad T430 is affected too. Got it fixed by setting "auto-mute" to "disabled" in AlsaMixer as described by Mike (thanks!). However, this workaround possibly causes a problem when switching (plugging in) to USB-soundcard (what never was a problem on Oneiric and Precise).
