Repeating Sound issue upon exit
#281276 - 04/02/12 07:47 PM


I'm going to post this on the Maximus Arcade site also since that's my front end, but I'm having this problem where when I exit out of a emulator sometimes the sound just repeats over and over like a machine gun and doesn't go away until I restart the computer.

Anyone experience something like this. It happens more on Newer 3D games usually.

Which emulators does this happen?

What soundcard is in your computer (if any) or if you're using onboard sound, what is your motherboard?

A uninstall/reinstall or checking for updated drivers might be your best bet to remedy this issue.

It's happened on all of them. Epsxe, PC games, Snes9x, Kusion, Project64, Mame64, NullDC, nes (forgot which).

I put in a sound card to actually try to eliminate this problem ASUS Zonar DG Sound Card.

Its gotta be a problem with Maximus Arcade because it doesn't happen when I just run them through Windows. MA has a Quit Executable function, but its as simple as a single button to do it.

Actually I just looked up my Audio card and that's a common problem. I just have to disable GX mode or whatever on it. I'll try that later when I get home.

Depending on your particular motherboard, you might need to put it in a different PCI slot. Some soundcards are VERY sensitive to IRQ sharing.

What krick said. There should be a table somewhere in your motherboard manual that shows which slots share an IRQ with other devices/slots.

If there's no slot available that doesn't share an IRQ, you can use one that shares IRQ with a device you don't use, like the serial port for example, or the on board sound if you have disabled that in the BIOS.

Kind of old school talking about IRQ sharing in 2012 isn't it.

It ended up being just the GX mode enabled in my Sound card software messed up the sound. I just turned it off and the problem never happened again.

Basic PC motherboard architecture hasn't changed much in the last 15+ years because they want to maintain backwards compatibility.

What has changed is that modern motherboards have multiple USB and SATA controllers as well as onboard sound, lan, and video all sharing the same FOUR IRQ lines reserved for the PCI bus. Every pair of USB ports is a single device, so boards sporting 8 USB ports actually have 4 devices fighting for IRQs.

Even if you disable the LPT (parallel) port, COM (serial) ports, floppy drive, and PS/2 keyboard and mouse, no additional IRQs are available for devices sharing the PCI bus. It's still limited to 4 IRQs total even if they shift around.

I know that some modern chipsets have moved certain devices like the LAN port off the PCI bus, but I don't know how that meshes with legacy device IRQs. It probably just steals one of the PCI IRQs, leaving only three.

I think this mess is part of the reason that there was such a hard push to move to an interface like USB where multiple low-bandwidth devices can be chained off a single port using a hub architecture.
