TROUBLESHOOTING TIPS
====================
for PHILIPS PCA761AW Audio Card
version 1.0P Date: 08/30/96
Symptoms: Your computer hangs, reboots itself, or issues a parity
error after the audio card is installed; a device in your
computer does not work properly since the card's
installation; or the system hangs when you enter or exit
Windows 3.1 after the card's installation.
Solutions: Determine and correct any conflicting I/O, IRQ or DMA
setting by performing the following steps:
1. Check the audio card's settings by referring to the
<Configuring Your Audio Card> section of the README.TXT
file.
2. Check your other devices' corresponding settings in
their respective setup utilities.
NOTE: If you have a LAN card, check its IRQ setting
first. Many LAN cards use IRQ 5 or 10; both
are used as the audio card's defaults.
3. Compare the card's settings against the settings of the
other devices.
4. Change the conflicting setting(s), i.e., setting(s)
shared by the audio card and another device in your
system. Although you can either change the audio
card's setting(s) or change the conflicting device's
setting(s), we recommend that you change the latter's
setting(s). Most of the audio card's default settings
are required by Sound Blaster games and therefore are
better kept unchanged.
5. Reboot your system.
Symptoms: The system requests you to insert the Windows 95 CD disc,
but after you have done so, it reports that it cannot
locate the interwav.drv driver file on the CD disc.
Solutions: This is a wrong request. In fact, the interwav.drv driver
file is located on the supplied driver diskette for
Windows 95 (Disk 3). Insert this driver diskette, change
the path on the dialog box on the screen from "d:\win95"
to "a:\" and press the "OK" button. This should solve
your problem.
This problem usually happens when you are reinstalling the
drivers after an uninstallation action (using the
"Uninstall" utility in the "Philips PCA761AW" program
folder) or when you are installing the PCA761AW drivers
after uninstalling another audio card.
Symptoms: There is no sound output.
Solutions: * Make sure that your speakers or headphones work properly
and are well connected to the audio card's SPK OUT jack.
* Make sure that the channel volumes are not muted by the
hardware (speakers or headphones) and software (any mixer
utility and currently run application) and are set high
enough.
* Make sure that the audio card is inserted properly in the
ISA slot.
* Make sure that the card's DMA settings are not used by
one of your other devices.
* If this problem occurred when you were playing a DOS-based
game, check your game software manual for any specific
requirements and the ways to meet these requirements. For
example, some games require EMM to play digitized voice.
Symptoms: There is no music or digitized voice or there is only
music in certain games.
Solutions: * Make sure that your AUTOEXEC.BAT file contains a line
similar to the following:
SET BLASTER=A220 I5 D1 T3
* Refer to application's user manual to see whether the
extended memory or the expanded memory are required.
Use a memory manager program to set up the required
memory.
* Increase the available memory by removing nonessential
device drivers and/or any TSR program from the memory.
Symptoms: Playing audio CD discs gives no output.
Solutions: * Make sure that the relevant mixer or other volume control
settings in DOS, Windows 3.1 and Windows 95 do not mute
the CD audio output and are set high enough.
* Make sure that your CD-ROM drive's audio-out connector
and the audio card's audio-in connector are properly
connected via the supplied audio cable.
* Check that your speakers work properly and are well
connected to the audio card's SPK OUT jack and the
speaker volume is set high enough.
* Make sure that the MCI CD Audio Driver supplied by Windows
3.xx is installed. Some applications require this driver
to play audio CD discs.
* Check your CD-ROM drive's user manual for information on
how to properly set it up to play audio CDs.
Symptoms: The audio card generates distorted or chirping sound
output.
Solutions: * Try adjusting the relevant mixer or other volume settings
in DOS, Windows 3.1 or Windows 95.
* Make sure that your speakers or headphones are not
defective or of poor quality.
* Try moving the card to a different slot to avoid possible
interference from its adjacent card(s).
* Determine and correct any IRQ conflict by following the
steps described in the very beginning of this file.
Symptoms: Your existing joystick does not work properly after the
card's installation.
Solutions: Disable the card's game port in the card's DOS-based
configuration utility or disable your existing game port/
game card by referring to the relevant user's manual. The
card's game port may be in conflict with your existing
game port/game card.
Symptoms: The joystick connected to this card's GAMEPORT/MIDI
connector is not working properly in some games.
Solutions: Try reducing your PC's CPU speed according to the
instructions of your PC owner's manual.
Symptoms: You cannot do a proper recording with a connected device,
such as your CD-ROM drive or microphone.
Solutions: * Make sure that the device is working properly and well
connected to the correct connector on the audio card.
* Make sure that you have selected the correct source of
recording in the mixer and recording software which you
are using.
* Make sure that the recording input level, monitor level
and the "gain" level has been set high enough.
Symptoms: There is no audio output when running Windows 3.1
applications, MIDI files cannot be played, or you get a
MIDI error message.
Solutions: * If a "Sound Driver Alert" error message telling you that
"Virtual device driver not present or Windows is not
running in 386 Enhanced Mode" every time when you enter
Windows, make sure that your audio card is properly
installed in the ISA slot.
* Check whether the MIDI Mapper icon appears in the Control
Panel and whether the "InterWave Audio Driver" appears in
the list of the installed drivers in the "Drivers" dialog
box (accessible through the "Drivers" icon in the Control
Panel). If not, reinstall the PCA761AW software with the
supplied diskettes.
Symptoms: There is no music coming from your DOS-based game.
Solutions: * Make sure that the "General MIDI Music [DOS Games]" is
enabled on the "Custom Configuration" panel of the
Installation and Configuration Utility (see Section 1.1 of
the README.TXT file.
* Make sure that the game application's synthesizer setting
is selected correctly.
Symptoms: The system responds with a not-enough-memory message when
running certain DOS-based games.
Solutions: The game applications you are running may require more
conventional memory than the currently allocated. Use a
memory manager program, e.g., the MEMMAKER.EXE program
included with DOS 6.2 or above or a third-party memory
manager program, to optimize your conventional memory
usage.
Symptoms: INTERWAVE or BLASTER variable not found or incorrect.
Solutions: Make sure that two lines similar to the following exist
in your AUTOEXEC.BAT file:
SET INTERWAVE=C:\PCA761AW\IW.INI
SET BLASTER=A220 I5 D1 T3
Applications that use Sound Blaster settings require
the BLASTER environment variable set in the AUTOEXEC.BAT
file, and the variable options must match the options
the applications use. Similarly, the utilities created
from the PCA761AW software installation process look for
the INTERWAVE environment variable to access the program
directory.
Symptoms: DOS-based applications fail with the message, "Need to
install Plug and Play Configuration Manager".
Solutions: Use the Intel ICU program to perform PnP configuration
for your system.
