Chapter 9: Troubleshooting
Unfortunately the Recording Control does not
work smoothly in this situation. The Video for
Windows device will always try to act like it is
the selected device even if it is not. You have to
manually enter Recording Control’s Options ->
Properties dialog to select your device.
If you no longer have need for the Video for
Windows driver, you can uninstall it using
instructions obtainable from Osprey technical
support. If you are comfortable using RegEdit
to edit your registry, you can instead go to the
following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows NT\CurrentVersion\Drivers32
Delete all REG_SZ entries named “mixer” or
“mixer1” .. “mixer9” that have the name of an
Osprey mixer as their data. These names will be
o2ca_mix.dll, o5ca_mix.dll, or o300_mix.dll.

Failed network connections, failure of a device
drive to initialize during start-up, or failure of the
Osprey card and driver to operate properly are
often traced to interrupt (IRQ) conflicts. In our
experience, IRQ conflicts are most commonly
seen when a PCI SCSI adapter, or possibly a PCI
network adapter, is present in the system.
Confl icts Between PCI Cards
PCI cards and drivers do not choose which IRQs
they use; rather, the operating system assigns
IRQ lines to PCI cards. The IRQ configuration
for the Osprey card or cards is determined
by Windows XP and the Osprey driver cannot
change this configuration. However, you can
cause the operating system to assign IRQs
differently by rearranging cards or changing
BIOS settings.
Multiple PCI cards are supposed to be able to
share the same IRQ line. In practice, occasionally
you may encounter a device driver that is not
implemented correctly for interrupt sharing. If
this problem arises, you have to rearrange the
PCI cards so that the non-compliant card does
not share its IRQ line with any other device.
Another problem is that some PCI device drivers
expect to use a particular IRQ line.
When a new card is added, it causes the system
to assign IRQs differently. If the IRQ assignment
for a particular card is changed and its device
driver does not detect the change, this causes
the system to work incorrectly.
The simple answer to this problem is it can
sometimes be solved by physically rearranging
the PCI cards such that their arrangement in
the PCI slots is different. When doing this, keep
careful notes of the arrangements you have
tried.
Another approach to PCI card conflicts is at the
BIOS level. Depending on what kind of system
BIOS you have, you may be able to change which
IRQ lines are allocated to PCI devices versus ISA
devices. You may be able to allocate more IRQ
lines for PCI devices and thereby solve a PCI
conflict.
Confl icts of PCI Cards with ISA Cards
A PCI card and an older-style ISA card can never
share IRQ lines. Unfortunately, if a device driver
for an ISA card has failed to initialize because of
an IRQ conflict, the card’s IRQ does not appear in
the list. To find the conflict, you have to examine
all your ISA cards with the Control Panel to find
out what IRQs they are trying to use.
If these approaches do not work, see Getting
Help in Chapter 1.
