Lenovo T61 Audio Pops Clicks Ubuntu 12.10


From Ubuntu's ALSA driver bug database [link here]:
This appears to be an old bug in kernel module snd_hda_intel (see /usr/share/doc/alsa-base/driver/powersave.txt and http://forums.opensuse.org/english/get-technical-help-here/hardware/388736-strange-pop-click-sound-speakers-every-time.html). 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-powersavechange the line

INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}to
INTEL_AUDIO_POWERSAVE=false
There's also something wrong with Unity 3D. Well, everything is wrong with Unity 3D, but here's the second bug report [link here]

What this means is that no remote -- other than the one that shipped with your device -- will work with your Dell Zino HD!  Scroll down to see my work-around. Since the Dell Zino HD only comes with 4 usb ports, the external sensor may have to be plugged in to the front of the device, which is partic
