I was thinking of updating the sigmatel drivers on an 8 yr old DELL. Would this give me better sound? I am using this Dell to run commercials and bumper music through a mixing board and into my HP computer we broadcast an internet/satalite radio show from. I want to get the clearest sound with little noise or digital noise. The Driver is a Sigmatel that came with the Dell when new.
So I am wondering if they have new improved drivers to work with the sound card or an update?
Looking for opinions? Am I wasting my time, and what are my options? Can I get a better Driver Brand set up to install with the current factory sound card or stick with what I got?
