Chapter 1. Questions
-----------------------------------------------------------------------------
1.1 The computer locks up or reboots.
Run SETUP and verify that your soundcard settings are correct:
- Check your I/O port address, IRQ line and DMA channel settings.
If you don't know your soundcard's settings, consult your manual
for details.
- Make sure your soundcard has no conflicts with other cards in
your system. If your soundcard works properly with other programs,
you can assume that there are no such conflicts.
If this doesn't solve the problem, try booting clean --- usually
memory managers like QEMM, EMM386, etc. and/or TSRs loaded in memory
may cause problems.
1.2 The sound system runs slowly on my computer.
Your computer is not enough fast. You can speed up the system by
running SETUP and setting a lower sampling rate.
1.3 The music sometimes skips like a broken record.
The sample rate setting is too high for your computer. Run SETUP
again and select a lower mixing frequency. If this doesn't solve
the problem, try booting clean.
1.4 The system does not recognize my soundcard.
You have selected the wrong soundcard or I/O port address. Run SETUP
again and select the right settings. If you are using a SB16 card
then you must check that the right drivers are loaded in your
AUTOEXEC.BAT and CONFIG.SYS files. If the problems persist, check
that you have enough conventional memory (maybe the system was unable
to allocate conventional memory required for a DMA buffer used to
communicate with your soundcard).
1.5 I can't hear any sound.
Probably the IRQ and/or DMA settings are incorrect. You must run the
SETUP program to select the right settings, it is highly recommended
to reboot your computer before trying the new settings.
1.6 The music sounds fine when I start, but it gets cut off several
seconds after.
This is what happens when you select a wrong IRQ line for your
soundcard. Run SETUP again and select the correct IRQ number.
Note: The sound system does not support IRQ lines higher than 7 if
you are using DOS/4GW DOS Extender. This is due to limitations of
this DOS extender. Use DOS/4GW Professional, DOS/4G or PMODE/W
instead to avoid problems with high interrupts. However, some of
the soundcard drivers may work fine, because these may not need
to use the IRQ interrupt line for playback.
1.7 My Sound Blaster clone is not recognized.
Run the SETUP program and set the right hardware parameters. Choose
the plain Sound Blaster. If this does not fix the problem, your
Sound Blaster clone may not be 100% register compatible.
1.8 The music sounds slow on my Sound Blaster.
Run SETUP again and tell it you have a plain Sound Blaster. Probably
you were using the Sound Blaster 2.0/Pro driver and your card does
not support high speed DMA transfers.
1.9 The system hangs with my Sound Blaster 16.
Your system's motherboard cannot handle high DMA at full speed. On
some machines, the DMA controller does not function properly during
high DMA transfer. To solve this problem, use a 8-bit DMA channel
for high DMA transfers. See your SB16 manual for details.
1.10 I hear static in my Sound Blaster.
Try turning the MIC and LINE volumes to zero (you can use SBP-SET.EXE
program for Sound Blaster Pro cards). If you still hear static try
disconnecting your parallel port devices.
1.11 I only hear sounds, but not music.
If you are using a GUS card probably the IRQ setting is incorrect,
run SETUP again and set the correct settings.
Chapter 2. Notes
-----------------------------------------------------------------------------
2.1 Sound Blaster 16 Notes:
You must select the high DMA channel in the SETUP program, this is
because the system uses 16-bit playback mode. See your SB16 manual
for details.
Make sure that the right SB16 drivers are loaded in the AUTOEXEC.BAT
and CONFIG.SYS files. If you don't want to waste memory loading
these drivers, you may want to try the following:
Edit your AUTOEXEC.BAT file and insert the following lines:
REM
REM These lines will setup your SB16 soundcard at port 220h
REM using IRQ 5, low DMA 1, high DMA 5 and MIDI port 330h.
REM
SET BLASTER=A220 I5 D1 H5 P330 T6
DIAGNOSE /S
The above lines will set your SB16 hardware configuration based on
the BLASTER environment variable. Make sure that the above lines
are setting the BLASTER variable with the right parameters. See your
manual for details about the BLASTER environment variable.
2.2 Pro Audio Spectrum Notes:
Make sure that the right PAS drivers are properly loaded in your
AUTOEXEC.BAT and CONFIG.SYS files. Without these drivers the system
won't recognize your PAS soundcard.
If you have a PAS+ or PAS16 and the system does not work properly,
you may want to try running SETUP and tell it that you have a
Sound Blaster soundcard.
2.3 Gravis UltraSound Notes:
You must choose the GF1 IRQ line and Playback DMA channel in the
SETUP program. Make sure that the right GUS drivers are loaded in
your AUTOEXEC.BAT and CONFIG.SYS files. However, the sound system
should work without loading any of these drivers.
Notice that some SB emulators (SBOS) may conflict with the sound
system, so if you experience problems try disabling these emulators.
