FAQ: SoundTrack Digital Audio 4ch/16ch
Note: we recommend to check the General
FAQ section as well.
hardware and driver related topics
1. Does the card work under Windows ME?
Please download our special driver for Windows ME (v3.2)
from this website. You might also need to download & install
the latest set of applications for the card.
2. Does the card work under Windows 2000/XP?
No, we did not release an official driver for Windows 2000/XP
for the SoundTrack Digital Audio 4ch/16ch cards. We do not
have the needed resources available to complete WDM driver
development for this card. The existing user base for SoundTrack
Digital Audio 4ch/16ch cards is very small compared to the
number of users of our other products. We apologize for this
situation and will of course continue to support our users
on the supported operating systems! This hardware was developed
a long time before Windows 2000/XP and audio applications
for that operating system have been released. On request we
can provide all the needed informations (incl. source code
of driver pre-releases) and support for third party developers.
3. Does the card work under Linux?
Yes, you can use the OSS-compatible driver by Gerd Rausch
which you can download on this
4. Is the SoundTrack Digital Audio 4ch/16ch Sound Blaster
5. Do I need amplified speakers or a separate amplifier
to use this soundcard?
Yes. Like most modern soundcards, there is no amplifier
on the card itself (because of the audio quality). This means
that you need active powered speakers to use the card properly.
Passive speakers without an amplifier will not give you enough
6. Can I output AC-3 signals with this card?
No, with current drivers and the common DVD player applications
this is not possible.
7. Is it possible to install this card in a system with
onboard-sound or another soundcard?
No problem! You should make sure that both devices do not
share their IRQ. It is not possible to install several SoundTrack
Digital Audio 4ch/16ch cards in one system. An internal combination
with the DSP24 by ST
Audio is even possible with a special digital connection.
8. Does this card support S/PDIF?
Yes. The optical and coaxial digital output connectors on
the optional SoundTrack Digital Bracket II / III provide optical
and coaxial S/PDIF connectors.
9. Is it possible to record bit-identical signals on the
digital input (I have the optional bracket)?
No. The hardware resamples all incoming signals with a high-quality
SRC chip from Analog Devices to 44.1kHz or 48kHz (depending
on the used software) which is in that case currently the
internal processing samplerate of the card. This does not
change the signal quality in a way that would be serious for
most -even real professional- applications. The used SRC chip
performs a better conversion (e.g. from 48kHz to 44.1kHz)
compared to many software algorithms in audio applications.
10. Are there any known incompatibilities with other hardware?
We do not recommend to use the card with mainboards using
the i810 chipset from Intel. The SoundTrack Digital Audio
4ch/16ch always needs an unshared IRQ to work properly and
in that case should work on all PCI 2.1 compatible mainboards.
11. What is the difference between the SoundTrack Digital
Audio 4ch and the SoundTrack Digital Audio 16ch?
The ST D_A 4ch card is using two SAM9407 DSPs from Dream,
while the ST D_A 16ch is using two SAM9707 DSPs. The difference
is that the SAM9407 provides one stereo input channel (2 channels
on 2 DSPs = 4 channels), while the SAM9707 provides four of
them (8 channels on 2 DSPs = 16 channels).
12. I heard about a SoundTrack Digital Audio 10ch ...
The ST D_A 10ch card was developed but never produced in
favour of the cheaper ST D_A 4ch. It was using one SAM9707
and one SAM9407.
13. I heard about a 'M' version of the SoundTrack Digital
The 'M' version was a revised hardware revision that could
be used (and was usualy bundled) with the DAC Bracket to support
a second stereo analog output (Rear) and MIDI I/O. The 'M'
version can be identified by the missing flat ribbon cable
connector left to the SIMM-socket (not mounted on the PCB).
software and usage related topics
1. Is it possible that my MD is creating new tracks automatically
when I am recording several WAV- or MP3-files via the digital
output of the digital bracket?
Yes and no. Sadly there is no standard for applications
and drivers to control a function like this. In most applications
you can use a special method to create new tracks: just add
(around) 3 sec. of silcence in the playlist between each track
in the playlist. You could use this
mp3-file for example. Some applications (e.g. WinAMP)
have special functions or plugins to support this. Of course
the breaks won't be on your final MD recordings!
2. When I start Windows, I get the message 'File Not Found
- DSP32.DLL' - where is this file?
This message does not mean that a file with this name is
missing. It refers to the driver that has not been installed
or loaded correctly. Either install the driver (if not done
so) or check for possible error messages that are displayed
on startup in text mode.
3. I get the error message 'C120' or 'C124' when I boot
by system in text mode. What can I do to load the driver?
Make sure the option 'PNP OS INSTALLED' in your BIOS is set
to 'NO'. This message can also appear if you have an IRQ sharing
problem (please install the card into a different PCI slot
then) or when the memory module on the PCI-card is not installed
correctly. Keep in mind that the ST D_A 4ch/16ch does not
work without a memory module installed. In some cases, this
can also appear when the PCI-card is not installed correctly
in the PCI-slot (mechanically).
4. I installed a new driver and the two colored lines
on startup are not displayed any longer. Still the card seems
Our Windows ME drivers do not show the init messages on
screen, don't worry - this is no problem.
5. I get the error message 'UNKNOWN CHIPSET' when I boot
by system in text mode. What's that?
No problem at all, this is no error message. This message
just indicates that the DAUDIO utility of the card did not
detect the exact model & type chipset of your mainboard (e.g.
it appears when you use a VIA chipset based mainboard).
