Wish I could use AwesomeMod...but every time I patch past 1.2.7 my audio stammers and stutters..thanks out to EA for the alpha software.
If that's your only problem there is a solution.
Background:
I had the same problem with stuttering sound.
At the beginning it was only me in the whole wide word with that problem. More and more people reported the same problem at thesims3.com but we are still very few. There was three echoes every 6:th second and by coincident I checked my sound drivers and I had three drivers. I removed one and I got two echoes and heureca!! I found it.
It seems that after the patch EA have opened sound channels to all available sound drivers or something.
There is another EA game called Dead Space that have exactly the same
problem and the solution is the same as we have found out.
http://forum.ea.com/eaforum/posts/list/32762.page On thesims3.com olivermypup describes what to do in proper english. The "Unimodem Half-Duplex Audio Device" we finally identified as the sound device for the internal dial up modem of type "Windows 56 kb software modem". If you really use dial up modem today I don't know what to do:

However I either missed one or it wasn't in the list before because I just tried it again, and there was a device listed that I don't remember being there. It's strange. I don't know how i could've missed it. Anyways I disabled it and sure enough the skipping has stopped. I am beside myself with joy! Apparently that is the issue. A thousand thank you's to Morphar!
Just to note, I figured out the device causing the issue on my system was "Unimodem Half-Duplex Audio Device" "
Some SimGuru have made a case at EA of this but no fix yet.
