On the bench today a Sound Blaster Pro 2 which only outputs noise. Let's test it and see if we can fix it!
Let's troubleshoot this card using a thermal camera, a microscope and let's do advanced electronic troubleshooting on FM sound generation by Yamaha! Also a good opportunity to improve on my microsoldering skills!
