(1) http://nielsmayer.com/npm/Screenshot-Efficient-Meters-Envy24Control.png
* To see what the new meters look like.
(2) http://nielsmayer.com/npm/Efficient-Meters-Envy24Control.tgz
* Contains levelmeters.c and x86_64 binary 'envy24control' that should at
least work on Fedora 12 and OpenSuse and other 2.6.32-based distros.
(3) http://nielsmayer.com/npm/Efficient-Meters-Envy24Control.patch
* To apply the patch, grab the most recent stable release (
ftp://ftp.alsa-project.org/pub/tools/alsa-tools-1.0.23.tar.bz2 ) or
git pull from trunk of the "alsa-tools" project.
* After unpacking and assuming you've got the patch in
~/Efficient-Meters-Envy24Control.patch.patch do:
>> cd alsa-tools-1.0.23
>> cat ~/Efficient-Meters-Envy24Control.patch | patch -p1
* It should give message "patching file envy24control/levelmeters.c"
* Follow the directions to compile alsa-tools.

FYI here's what my "top" processes look like when running a test to
output individual streams to all 10 PCM output channels -- note X
consumes between "1.7%" to "2.0 %" and "envy24control" "0.7%" to
"1.0%":

Here's the envy24control from my first patch, using the original
meters that cause many separate XDrawRectangles for each LED-looking
segment. The performance difference is quite noticeable as the fans
start running louder and the system load climbs upwards as soon as the
original envy24control starts running: X consumes 5.7-10% CPU, and
envy24control between 2.0% and 2.7%.

Just to show that it's the same performance as the original
envy24control from alsa-tools-1.0.22-1.1.fc12.ccrma.x86_64:
