M-Audio Dman PCI [22/29] Troubleshooting

Troubleshooting

This section addresses potential problems that can arise in all operating system

environments, with emphasis on hardware troubleshooting. Within the PC

environment there is a limited number of hardware resources (Addresses,

IRQs, and DMA channels) available for use. Most audio card installation prob-

lems arise from improperly set IRQ values. Please see the section Windows

Driver Configuration to review the proper settings for your computer.

Problem: My computer won't boot when I installed the DMAN PCI card, or,

I got a Fatal Exception blue screen.

Possible Cause 1: A version of DirectX 5.0 or better has not been installed in

your system. Remove the DMAN PCI card, then restart Windows. Follow the

software installation as described in the section, "Windows Software

Installation." Next, follow the procedures described in the "Hardware

Installation," and "Restarting Your Computer for the First Time" sections.

Problem: The DMAN PCI does not show up in my Device Manager, nor does

the card work.

Possible Cause 1: Proper procedure for software and hardware installation has

not been followed. DMAN drivers must be installed first, as well as a version

of DirectX that is at least 5.0. See the sections, "Windows Software Installation,"

"Hardware Installation," and "Restarting Your Computer for the First Time."

Problem: No sound on either recording or playback.

Possible Cause 1: Improper connections of the audio accessories. Verify that

the Line Out is properly connected to an external amplifier, powered speakers

or mixer. Also check your audio source and verify that its levels are turned up.

Possible Cause 2: Improper volume control adjustment in the mixer. Two vol-

ume controls affect the sound level of each audio device (Output Level and

Master Volume) -- make sure none are set too low or muted. See The Windows

Mixer (WSS Mixer) section for more information.

Possible Cause 3: Recording source is not properly selected in the Windows

Record Mixer. See The Windows Mixer (WSS Mixer) section for more informa-

tion.

Possible Cause 4: There is a resource conflict with another device in your com-

puter. This is more evident during the recording and playback of digital audio

than in monitoring the Line In. Check the DMAN PCI configuration (Address

and IRQ) against those of the other devices on your computer. If necessary,

change the settings for the one or more of the devices.

Problem: Repetitious Sound.

Possible Cause: Wrong IRQ or IRQ conflict. Often this will result in a small

segment of sound (0.5 to 1 second) repeating itself over and over, sometimes

completely locking up the computer. You will need to change the IRQ setting
