I have two sound cards, Realtek High Definition Audio and Intel Display Audio. How do I know which is default for listening to music and playing games (Realtek sounds better)? I have an Acer 5755G laptop that I use with external speakers. Is there any problem with this? Are there any side-effects when you plug the laptop to a huge 5.1 audio system (which is meant for the tv)? I am looking to buy new speakers, which speaker will be compatible with my laptop?
