Hi everyone, I'm having a big problem. I finally got all my new hardware today, and it's nice. I now have a GS with the following: Harris Labs GSSauce with 2 megs of DMA RAM \ Apple DMA SCSI card (DMA turned on, obviously) > All brand new Segate ST1096N 84 meg SCSI drive (ooh, it's nice!) / MDIdeas SuperSonic Stereo card and digitizer plus some other stuff... Here's the problem. Everything was working just dandy until today. I had everything but the Segate and the SCSI card hooked up and working. The drive came in the mail today, so I naturally hooked it up and copied everything off of my old drive onto the new one. I'm now having what I consider to be a pretty big problem. It seems that the DMA is upsetting the stereo card. If I try to play a sound using either the PLAY exec file, or the Greetings init, or the BGSound CDA, I get nothing. Oddly enough, if I play a digitized sound in BGsound TWICE, it works the second time. My guess is that since the sound is already in RAM, the DAA card doesn't have a chance to mess things up. If I use SoundEdit, or some such program, the sound plays fine. My guess again, is that since it's already in RAM, the DMA SCSI doesn't have a chance to mess it up. I tried booting the system with DMA off, and it bombed while the system was still loading. Besides, I bought a new RAM card so I could use DMA... I'm not about to turn it off. Let me clarify something: When Greetings plays the sounds as the system boots, it plays through the internal speaker, but not through the SuperSonic. Has anyone else ever heard of this happening? Is there a fix for it? Is it my Stereo Card, or is it that the signals aren't making it to the sound output jack on the motherboard? By the way, for those interested, I'm going to post about the drive, card, cable, ram card, etc. Kind of a review of all the components, and what's needed to make everything work with each other. -Greg T.

Try booting up a mega-game like Task Force or Rastan or Alien Mind or mega-demo like Modulae or Nucleus. Those programs don't use the sound tools so that may be the problem. BTW, you _DO_ have the new SCSI drivers installed, right? THey come with the dma scsi card. You must install the system first and then the new drivers. You may wanna wait till the end of the week, Apple will be officially released 5.03 by then (hopefully). Its already shipping on a few commercial products. .
