First, this is not meant as an 'attack' on Soundblaster. I know a lot of people use them successfully. It's merely meant as an aid to anyone who may have unexplainable problems with their computers.
When I had my Soundblaster Audigy installed in my PC, I started having a lot of problems with my DXLabs applications and MultiPSK. Strange error messages and performance issues. The DXLabs author spent a great deal of time trying to diagnose these problems. Finally, I decided to try the built-in sound card, and wouldn't you know, all the issues cleared up. Happy to have found the culprit, I replaced the Audigy with another Soundblaster card, since the on-board card doesn't work well for digital radio. Little problems began to show up again. Once in a while, the PC wouldn't boot properly, but most of the issues were with digital ham apps. Beginning to see a trend, I just replaced the Soundblaster again, but this time with an inexpensive Diamond brand sound card. All problems have completely disappeared! This isn't an ad for Diamond sound cards, or a blanket condemnation of Soundblaster. Just a hopefully informative note to anyone out there who has problems with their PC that are unexplainable by other causes, that looking at your sound card /*might*/ be a place to look. 73 Dave KB3MOW
