[RESOLVED] How to change sound card IRQ?

[Zebroxxy]

I have been baffled recently as to why my Intel PC Camera Pro refused to work under Windows XP even though it had a built in driver. The cam would go ok, but real choppy for a couple minutes before locking up. Then I discovered the root of the problem thanks to a newsgroup posting by someone. The IRQ of my soundcard is 11, and thats also the IRQ of some ATA100 RAID controller, but the real amazing thing is when I disable the sound card, the cam works like magic, no more freezing up etc. But I want to be able to use the cam and the sound card, so does anyone know how I can get the sound card OFF of IRQ 11? I would really appreciate it. thanks

There are a few things to try, each one more work than the previous.

1 - boot to safe mode, remove all sound card related items from device manager, reboot and redetect - hopefully it will move on its own.

2. - boot to safe mode, removall sound card related items from device manager. Shut down, remove card, reboot, shut down, install card and reboot and detect, hopefully with a new irq

3. - as for two, but move the sound card to a different slot.

4. - as for 2 but go into bios and turn off the pnp os aware and assign irqs to each slot.


All I can say is, have fun!

Sounds like an ACPI issue to me, to which you cannot reassign resources within windows without changing the HAL (HArdware Abstraction Layer) to Standard PC.

You could try this though, but it may not work, but it does the vast majority of the time.

Open Device manager Expand the 'Computer' section of the device tree Double click Advanced Configuration & Power Interface PC Click the Driver tab, then Update Driver On the new pop-up box, select 'Install from list or specific location (advanced)' Select 'Don't search' Uncheck the box on next screen for 'Show COmpatiable Hardware' Select Standard {PC from list Finish the installation & reboot. Windows will then redetect the hardware again, and will then use the Hardware assigned resources, as set in teh BIOS & the actual hardware itself.


If this doesn't work (it does on 2 of the systems here with XP on and the other one it won't), then the only way to sort this out, is to reinstall XP and press F5 where it says to Press F6 to install a third party controller (yes I know it says F6 but F5 allows you to change the HAL selection)

Thanks for the responses guys, I found out a little more today. Turns out when today I went into system information, I found a whole slew of things hogging IRQ 11. These devices werent listed under IRQ 11 before, just now they are. Here is what all it says under 11, Microsoft ACPI-Compliant system (and no the comp doesnt shut down correctly)Nvidia Geforce 2 MX, VIA Rev 5 or later USB Universal Bus Controller (2 of these) Kingstone EtherX Ethernet Card, Creative AudioPCI, HPT370 UDMA/ATA100 RAUD Controller. All of those items are showing IRQ 11 now, and before it was just the Creative sound card and RAID controller. The only change I have made is installing Roxio EZ CD 5.0 which I think could be to blame. Anyway, Intel is completely unable to help, and since a friend built the system I have no manufacturor to find out how to fix this from, so any help with this is most appreciated. Thanks

[Darren Wilson]

It is as I said in my previous post, it is all down to ACPI. Without turning ACPI off in both the Hardware & software, you will not be able to do anything about it.

It is not Roxio that is causing the problem.

Follow the steps above that I posted, if they do not work then you will have to reinstall Windows in standard mode by pressing F5 on the very first setup screen.

Darren - I followed your steps above, and when I rebooted everything got mass detected again, and now it is back the way it was before, only two things in IRQ 11, Creative AudioPCI soundcard, and the RAID controller. A friend said to check the properties for each device and go to resources to try to force change the IRQ, but the checkbox for Auto assign is greyed out. So I have Sound card and RAID controller on IRQ 11 and a cam that doesnt work =\ Not sure if reinstalling windows would make a difference, unless it does something different than changing the ACPI to Standard PC

[StevePorter]

Zebroxxy, Darren's giving you the right direction to resolve your problem. ACPI allows more than one device to share interrupts (IRQs) without a problem on most computers. Otherwise, you'd run out of IRQs for all your different computer devices.

Another consideration: make sure your motherboard's BIOS has been upgraded. Any BIOS dated before 01/01/99 is suspect, but the later the better... http://forums.windrivers.com/cgi-bin/forum1/noncgi/cwmsmilies/cwm35.gif

OK I see where it is going now.

Zeebroxy, move the Sound card to a different PCI slot as the slot that the sound card is currently in is sharing the resources (as set in the actual motherboard itself) with the onboard RAID controller. I have a similar problem with m Abit KT7A-RAID if I place the sound card in certain PCI slots.

Darren - good plan, will try that tomorrow, btw, my motherboard is an ABIT KT7A , hehe, so that may be it, although its the version without raid

Now we are talking!!! this should be quite simple now then if it is a KT7A (I know these like the back of my hand) http://forums.windrivers.com/cgi-bin/forum1/noncgi/biggrin.gif http://forums.windrivers.com/cgi-bin/forum1/noncgi/biggrin.gif

OK here is how the Abit KT7x shares it's resources.

AGP - Shares with PCI#1
PCI#1 - Shares with AGP
PCI#2 - Shares with PCI#3 & ACPI (if installed)
PCI#3 - Shares with PCI#2 & ACPI (If installed)
PCI#4 - Shares with PCI#6 & USB Controllers
PCI#5 - Shares with Onboard HPT370 (on KT7A-RAID)
PCI#6 - Shares with PCI#4 & USB Controllers

<font face="Tahoma, Arial, Helvetica, Verdana, Geneva" size="2">Taken from Paul's KT7-FAQ
If you have an AGP card and two PCI devices, but no ACPI, USB or HPT370 enabled, you can put those devices in slots 2 and 4, 5 or 6 slots 3 and 4, 5 or 6 slots 4 and 5 slots 5 and 6

If you have an AGP card, two PCI devices and ACPI, but no USB or HPT370 enabled, you can put those devices in
slots 4 and 5 slots 5 and 6

If you have an AGP card, two PCI devices and USB, but no ACPI or HPT370 enabled, you can put those devices in
slots 2 and 5 slots 3 and 5

If you have an AGP card, two PCI devices and HPT370, but no ACPI or USB enabled, you can put those devices in slots
2 and 4 or 6 slots 3 and 4 or 6

If you have an AGP card and two PCI devices and ACPI and USB but no HPT370 enabled, then
slot 5 will have its own IRQ

Other than the above combinations, your PCI cards will always have to share an IRQ with at least one device. But, to re-iterate, with a modern properly designed PCI card this is not a problem! The PCI standard is designed to allow the sharing of IRQs.
</font>

Also if you are using a HPT370 card (which you are) remember to reserve IRQ5 in the BIOS to Legacy/ISA, else you may get problems with your sound card conflicting with it. Also DO NOT let your NIC & Sound Card, share IRQ's.

(not being able to look at my mobo right now) I know I have a PCI RAID controller, a PCI soundcard, AGP vid card, i think the 56k modem is ISA, a PCI ethernet card, ACPI enabled, 2 USB ports enabled. Not sure off the top of my head what is in what slot, do you have any recommendations for how all these devices should be placed, PCI slot-wise? Not sure atm what is sharing with what or if its causing problems. thanks again

[Darren Wilson]

First you will need to disable ACPI like i stated in the other post else the following will not be applicable at all.

AGP Card - Obviously in the AGP slot
PCI#1 - Empty
PCI#2 - Sound
PCI#3 - Empty
PCI#4 - NIC
PCI#5 - PCI RAID Controller
PCI#6 - Empty
ISA#1 - Modem (Obviously) *Set IRQ to use #5 if possible as you have reserved it for Legacy Use in the BIOS*
