Listers, I'm building up (via swap) an 8500 for making analog video Quicktime movies with a Sharp video cam. I have it set up (so far) thus: 4 hd's; 2 x 4.3 gig scsi SCA's with adapters installed in the bays( thanks Jerry B.), and a 27 gig and 40 IDE (thanks Jamie P.) running off a tweaked ATA 66 card (thanks Jeff W.). The machine has OS X.1.3running on one of the 4.3's (loaded via XPost Facto) and OS 9.1 on the other 4.3 and the 27). OS X does not see the ATA card, so X is (for the moment) a curiosity only. On the 27 gig I have Quicktime Pro 5 and Strata videoshop 4.5. I have a LitOn 40x10x48 cd-rw in the machine( thanks Jamie P.) The machine has 768 mgs ram (thanks Bruce G and John McG.) I need suggestions for proceeding and I have a problem. The problem is that the audio volume is very low. It was low out of the 8x cd-rom that the LiteOn cd-rw replaced too. I have the main volume and the Apple CD Audio Player volume turned up. How do I problem shoot for a software problem? And how do I problem shoot for a hardware problem? (other than swap out the MoBo, which I trying to make a last resort). -- All the best, R.A. Cantrell <racan at flash.net>
