I've had a recurring problem with sound and my wireless NETWORK connection for a few weeks; I can't remember anything I could have installed or done that would have started this, other than possibly installing WinAmp. I haven't installed any new hardware for a year or so.

I have an M-Audio Delta sound card and a D-Link PCI wireless network card. I access the internet through the wireless network. These have HAPPILY coexisted for a couple of years until the current trouble. I'm using XP Professional SP2.

If I use any sound application on the PC - e.g. playing music in Winamp or Media Player, or sequencing in Cubase - the network connection is dropped. This happens between 5 and 10m after starting to use sound. I can click the option to 'repair' the connection and this works each time.

If I use sound while actively on the net, e.g. Quicktime movies, often the sound will simply STOP after a few minutes, and only a reboot will bring it back.

I've uninstalled the drivers for the sound card and reinstalled them, but it made no difference.

Here are the IRQs:
IRQ 0 System timer OK
IRQ 1 Standard 101/102-Key or Microsoft Natural PS/2 Keyboard OK
IRQ 3 Communications Port (COM2) OK
IRQ 4 Communications Port (COM1) OK
IRQ 6 Standard floppy disk controller OK
IRQ 8 System CMOS/real time clock OK
IRQ 9 Microsoft ACPI-Compliant System OK
IRQ 10 Multimedia Controller OK
IRQ 12 Microsoft PS/2 Port MOUSE (IntelliPoint) OK
IRQ 13 Numeric data processor OK
IRQ 14 Primary IDE Channel OK
IRQ 15 Secondary IDE Channel OK
IRQ 16 VIA Rev 5 or later USB Universal Host Companion Controller OK
IRQ 17 M Audio Delta Audiophile OK
IRQ 18 VIA USB Enhanced Host Controller OK
IRQ 19 D-Link AirPlus DWL-520+ Wireless PCI Adapter OK
IRQ 19 NVIDIA GeForce4 MX 440 OK
IRQ 20 Standard Enhanced PCI to USB Host Controller OK
IRQ 21 Standard OpenHCD USB Host Controller OK
IRQ 22 Standard OpenHCD USB Host Controller OK

I notice that my graphics card and the network card are sharing 19, but the sound card is on 17.

Can anyone help?Check the resources tab for each of the suspect devices in Device Manager - this will show if there is a conflict or not.

Also try going into your BIOS seeing if you have an option to Reset Configuration Data or Clear SVRAM, this forces the PC to re-assign the IRQ's for all of the devices on reboot.

You never mentioned if you had tried re-installing the drives for the network card or updating either driver.
Try these as well.

My NIC and VGA card use the same IRQ as well so that's not the problem.In Device manager, under 'other devices' I have a Multimedia Controller in PCI Slot 7 (PCI bus 1, device 9, function 0), for which it says no drivers are installed. It has an exclamation mark. Also under 'other devices' it lists an Ethernet controller and an SM Bus controller, both disabled. I'll try disabling the multimedia controller and hope I don't lose my picture!

The sound card is in PCI slot 6, no problems or conflicts reported.

The network card is in PCI slot 4, no problems or conflicts.


I have downloaded and installed the latest driver for the sound card but not yet for the network card.If it lists anything under 'Other Devices' then the system knows what they might be but as you say doesnt have the drivers for them.

You'll need to get the drivers for the sound card and the ethernet controller. The SM Bus controller should be installed either through SP2 or your motherboard drivers disc.I don't even have an ethernet controller (assuming that means a cable network card)!

My PCI slots have:
- a USB2 hub
- a TV/DVD video card that I don't use (would that be the multimedia controller?)
- the sound card
- a single USB port (is that SM Bus?)
- the network card
- my video card.

The sound card has the latest drivers, downloaded and installed today. Sound plays for about 3m then cuts out.
Hasn't disconnected the network yet, just cut itself off, which is worse because you have to reboot to get it back.

Any other info I can give you that might be useful? I'm going to try the BIOS operation you suggested.

Try dis-connecting the card you are not using and removing it from Control Panel...

patio. I think the problem is resolved. I went into BIOS and did what you suggested, and while there discovered the onboard sound device was also enabled, which it shouldn't have been. So I disabled that and disabled the 'questionmarked' things in Device Manager.

I've had well over ten minutes of sound playing without any cutting out or affecting the network.

I had to reinstall my Cubase sequencer as it wouldn't open with the new audio card drivers but after reinstallation it was OK.

I'll monitor for a couple of days now and see if it really is fixed. Thanks very much for your time and advice.
