Hi there, recently partly patched my win98se system via AutoPatcher98_Dec.2007 (modules: Stability Hotfixes, Internet Explorer, Recommended Tweaks - Turn on DMA access to your storage devices) Except a certain sound Issue (spoken sound stutters in MS Flight Simulator 9) everything works very well. Tried several adjustments to fix this. Updated drivers for my sound card (Sound Blaster Live! 24-bit), lowered its hardware acceleration in the audio tab, increased and decreased its latency, checked its IRQ (to be separated from any other device) and switched off any Directx (version 9c) debugging. Dxdiag tab tells me everything works well. Does anyone have an idea what could be wrong? I will be very greatful to any reasonable answer.
