I know this is more of a hardware question but I'm sure you guys can help me out!Well I just bought a Yamaha 6416S CD Writer connected to an Adaptec 2903B SCSI Card.
The SCSI Card and my sound card, SB Live are sharing the same IRQ and I couldn't get the Yamaha to work because of the conflict that resulted. When I disabled SB 16 emulation it seemed okay, then I tried to make my first CD. The result was, as Dragon says, a coaster - half of the tracks were wrong or started somewhere in the middle of the song. I wonder if this could be due to the IRQ sharing between the sound card and the SCSI card....need advice!!
 
It's not a good idea in general to try to share IRQs between your sound card and other devices. Are there none left you can use?
 
Ouch, Rolland! Well, the good news is that you can temporarily get going making CDs...just pull out the conflicting sound card, and you'll be living proof of my oft-repeated assertion that burning CDs has nothing to do with the sound card! It would be great to hear someone actually prove it...

More long-term, though, you'll have to solve this problem. Most new cards (PCI at least) can use damn near any IRQ and the plug-and-pray BIOS straightens it out. Are you running some ancient legacy ISA cards by any chance?
 
My IRQs from 1 to 15 are all used up. The CD-R and sound card use number 10. Both my Adaptec SCSI Card and SB Live sound card are PCI. I don't think I have any ISA cards. And how do I change the IRQ for the devices? Windows always says they can't be modified.

Well I did some experimenting yesterday and eventually disabled SB 16 Emulator (which apprently was causing the conflict) with Sound blaster still enabled, and after that I burned a couple of succesful CDs even though they were still sharing the IRQ. (I wanted to take Dragon's advice on the sound card too, but after some long consideration, I suddenly realised that if I did, there would be no sound! :)

I'm not sure also if the writing speed had something to do with it. The first time when I recorded the failure, it was at 6X. All the CDs I made at 4X were okay. Do you know whether the write speed has an effect on the success of the CD?

Thanks!
 
im pretty sure that a higher bad burn rate comes with the territory when you try to burn at 8x... the lower the burn rate , the less likely you are to burn a bad cd.. but... knock on wood , i burn at 4 times and have never had a bad burn yet ...

i think maybe your burning at 6x on a cd that only supports up to 4x burning.. but depending on your software , you might not even be able to do that... i had a 4x writer and the media that came bundled only supported 2x... so the software wouldnt let me burn at 4... hope this helps....
