M-AUDIO Dman PCI - Manual (Page 22)

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
