Strangely however, I only observed this after upgrading to Precise AND installation of a new battery in my T61p Thinkpad. In any case, turning off Intel audio power saving works around the problem: In /usr/lib/pm-utils/power.d/intel-audio-powersave change the line INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true} to INTEL_AUDIO_POWERSAVE=false I am only filing this bug report since finding the workaround for specifically Precise (and other recent Ubuntu distros) required a bit of time (to put 2 and 2 together). Hope others won't have to spend the time now.
