Is it possible to upgrade the sound card for a HP Pavilion zd8000 yourself? I know this might sound dumb, but I am trying to build a laptop to use along side my digital recorder (Korg D1600). I know my Korg has 16 and 24 bit resloutions for recordings, and I use 24bit exclusively. If I were to ever do any editing by computer to my tracks, would the fact that the HP Pavilion zd8000 has a 16bit sound card effect the quality of sound I would hear? I'm not sure whether this should be posted somewhere else or not. Any suggestions?
