doesn't happen to me on June 2007 MacBook, with Hardy x86 edition. (although, after upgrading to Hardy, I had to use the workaround in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/201957 for any sound at all to come out of my headphones). Now, maybe it's different on your different configuration or when the Ubuntu is 64-bit. For me, even if no sound comes out of the headphones, if there are any plugged into the headphones jack then no sound comes out of the built-in speakers.
