Hi all
A7V8X-MX and Creative Soundblaster live 5.1
I have the above combination, XP Pro, latest XP Live Drivers for the
soundcard, on-board sound disabled in bios. No other sound drivers
appearing in hardware list. Latest 4 in 1 drivers.
Sound randomly goes into machine gun style stuttering mode whilst playing
CD's or mp3's.
Any ideas?
Try placing the sound card in slot 2 or slot 3.
(If in slot 1, the sound card will share the same IRQ
line as the AGP card.)
Try setting "PCI Delay Transaction" [Enabled] in the BIOS.
(Delay Transaction decouples slow peripherals from the PCI bus.
An outstanding request is retried at intervals, allowing other
bus transactions to happen while waiting for a slow peripheral
to respond. Accesses to an IDE disk drive seem to count as
"slow peripherals".)
Hi Paul
Thanks for that. The card is in slot 2 at the moment. Off to the bios to
try your PCI delay transaction suggestion.
Checked the bios - PCI delay transaction already enabled.

Next step is software. While playing your CD's, bring up task manager
and see whether any printer software is being forked. It could be
an issue with a driver tying up the system for a short time and
preventing a sound card interrupt from being serviced. Have a look
through the task list and see if there is anything running that
shouldn't be.
I have got the answer from the Asus FAQ - I was searching for Soundblaster
instead of SB!
The Creative sound card requires two IRQs; one is for SB16 Emulation (ISA
IRQ) and the other is for the sound card itself (PCI IRQ). An IRQ for
legacy device should be used for DOS emulation. Since A7V M/B does not have
ISA slots, the BIOS assigns all IRQs to PCI. Therefore, you need to change
the BIOS setting in order to assign an ISA IRQ to the card. Please set
"IRQ5 Reserved for legacy device" to "Yes" under Advanced -> PCI
configuration -> PCI/PNP IRQ Resource Exclusion in BIOS.
The bios on mine isn't quite the same but I eventually managed to assign
IRQ5 - reserved for legacy device. Problem solved.
I assume by disabling the legacy driver I would have also solved the
problem.
Thanks for all the input - it was very much appreciated.
