Interessting. I got the sound delay with SD material (mjpeg) too. Perhaps 
Ubuntu 12.04 runs not pretty well on my hardware actually. 
I will investigate more this evening. 
 
Regards,
Erik

No sound delay when editing in SD (.dv or .move) or HD (.mov).
When trying to edit directly with .mts HD, I get a delay. Can offset
    audio by about 0.48, and it's close.

If I have talking heads where sync is critical, I reformat into
    dnxhd codec in quicktime (.mov). Everything works better with a
    cinelerra friendly codec.
Only use .mts directly for quick and dirty edits.

cheers

        the Grandma manual to switch to esound in the preferences. The
        result is no sound at all.
