GPL, SB Live: popping

I have been running a sblive value in a celeron 300a@450 system with no problems. I have now upgraded to a abit bh6-1.02, celery coppermine 533@800 and now getting popping/scratching when running GPL. Not extremely bad, just enough to be annoying. Some details: Music cd's are fine GPL popping sound is not intermittent, always there in GPL Installed latest sblive driver, just driver, not full liveware3.0 installed directx-7a from 6.1 installed latest 3dfx voodoo3-2k drivers (agp card) switched sblive to other slots sblive dos emulation disabled and commented out in autoexec sblive gameport disabled (using acm gamecard for naspro pedals) No irq conflicts, I can control irq assignment and have moved the sblive, v3-2k, and usb assignments around, no luck. I have 2 free irq's. Current, sblive=irq9, v3=10, usb=11, irq5 and 7 are free. In GPL, I have always used the Thomas Brown version 2.0 sounds. I have moved those files out of way, used GPL original sounds, same popping noise. hardware: abit bh6-rev 1.02 celery coppermine 533@800 sb live value voodoo3-2k agp act labs force rs wheel, serial acm gamecard for thrustmaster naspro pedals maxtor 8.4g Any ideas? Thanks...Chuck

I've had similar popping/crackling when playing WAV files on my Live. As an experiment disable UDMA for your IDE channels in your BIOS and see what happens. If the problem clears then you have one of the motherboards that has this problem when using UDMA access for the IDE drives and the PCI bus that the SB Live is using. I leave my UDMA disabled most of the time now because the crackling really gets on my nerves and the performance of the PC isn't noticeably reduced by disabling it.

Have you tried leaving it enabled in the bios but disabling it in device manager in Windows? Just double click on your hard drive entry, click settings, untick the DMA checkbox. I think this can have a different effect to just disabling in the bios, so it's probably worth a try before you do anything else.

Come to think of it, I remembered another thing to try. The following from the SBLive newsgroup: "Try changing the DMA buffer size by doing the following steps: 1. In the Device Manager, go to System Device to the properties for the Direct Memory Access Controller. 2. On the Settings tab, under reserved memory, check the box for Reserve DMA buffer. 3. Select a range of 64KB for the buffer and click OK." Hope this helps. Cheers, Neil Neil wrote:

I tried this after your suggestion, bios ide1 and ide2, master & slave, udma disable, still popping/crackling. GPL does it, and I can tell right away that it will since welcom98.wav does it also.

I know it sounds obvious, but make sure you have the latest motherboard, and sblive drivers. I installed the latest ones for my VIA abomination, and the popping went away !.

Neil, tried this, no help, thanks. Neil <[email hidden]> wrote: : Have you tried leaving it enabled in the bios but disabling it in device manager : in Windows?
