Winmodem and On-board sound device conflict
I just purchased an Aztech 56K winmodem. I am proficient in Win95 and dealt with all hardware conflicts O.K. Regardless of how I configure it however, I run into an intermittent problem with Windows sounds looping through my on-board sound device (SoundPro). I have moved VGA and Modem to other PCI slots to change the order they are loaded but still to no avail. Also - it appears to be worse when a sound is attempted while connected to the internet using this modem.
Couple of questions... What IRQ is the sound card on? It works best on 5 and Windows sometimes has problems when it is on higher IRQ's (it likes to put it on 10 for some reason), though if it is a PCI card, I'm not sure if you can put it on 5. WinModems are known to have problems, at least the USR ones, never heard of an Aztech. Is the modem a voice modem? That could be a problem...
Can you give us more about your system? Resources of the modem and sound card and type of system (processor, ram, etc). Can you assign resources for the on-board sound in the bios?

I have all of my IRQ's used up. So, I forced my network card to the IRQ currently being used by the sound card so that it would be re-assigned a different IRQ after booting. So far everything seems to be O.K.
Thanks for your help.
Thanks for your help.
it's possible for some (PnP)devices to share the same IRQ, if you run out of them; another option is to disable one or more com-ports.

How do I know when a pnp device can share an IRQ? Device Manager will always show a conflict won't it? Also, what common devices can share IRQs? I know that the COM2/COM4 and COM1/COM3 share but I have also had conflict when devices on both ports are to be used at the same time.
