With LTS 10:4 I was running out of space to perform updates with my 4 gig original HD. I was also loosing sound on update, and I figured it was because I was removing open office etc to get extra space. After doing the update I would have no sound.
I finally gave up and bought the run core 16GB as an update. I then installed 10:4, had sound, run the updates no sound. So I switched to 11:10 (won't run with a 4 GB HD), had sound, did the updates still have sound.
FYI, I did live USB, did the additonal drivers to get wifi (finally did have to cat 5 to the Internet to get it to work). Since the live usb was persistent, when I booted again to do the install, wifi worked, was also to get the media codecs to install during the build.
