Audigy2 SB0240 Crashes WinAMP after 1 to 4 Hours of Playing
You can restart WinAMP by Killing it Device Mgr and Continue.
I run an Athlon 850 on a K7t 133 and 868B southBridge that has addressing issues with Cards with no PCI Parking - but I had the SB Live! with no PCI Parking working great as long as it shared an Irq with the AGP and PCI Delay Latency Disabled in BIOS.
The Audigy2 has PCI Parking, so I Installed the Audigy to a slot with it's own Irq such that : Slot 1 is AGP , Slot 3 TV Capture, Slot 5 SB0240 and Slot 7 NIC - In this case the MB BIOS assigns each card it's own Irq and none are shared - however NT ACPI does regulate Irq Assignment and report all devices as Irq3
SB0240 Drivers are latest from Creative Labs
Anyway : the problem of WinAMP Crashing after some time persists even if I ENABLE PCI Delay Transactions - I've tried various versions of WinAMP and Same thing - I'm now playing with Buffering in WinAMP Preferences/OutPut/Direct Sound OutPut - SO FAR NO GOOD
Have you noticed that "CICEROUIWNDFRAME" Process, a speech engine for Office I believe hangs if you ReBoot when WinAMP Crashes.
I have also Blown all DUST out of the Tower and all 4 fans running Good.
Siish!! a 2 to 4 hour TEST to see if WinAMP Crashes Gads!!!
If it's NOT a Buffer over run in WinAMP then it could possible an Audigy2 Driver leak - but this would freeze the System and that's not happening.
Heat - can't see that as my case is open and 4 fans running - unless the Audigy2 has a defective Chip that overheats.
You and I seem to be the only ones afflected with this problem - so a defective Audgy2 may be reasonable to conclude.
I'll post my updates - if I find something out with in 3 days or this Card goes BACK
SafeMode
