FAQ: SoundTrack Digital XG / i-Phone XG
Note: we recommend to check the General
FAQ section as well.
hardware and driver related topics
1. Does the card work under Windows NT 4.0?
Yes. The NT 4.0 driver is supplied with the card (check the
included CD-ROM) and can be downloaded on our website.
2. Does the card work under Windows 2000 or Windows XP?
Yes. The driver can be downloaded on our website and is now
also included with the card on the CD-ROM. For Windows XP
you can either use the driver that is built into Windows XP
or our updates from this website (recommended). We strongly
recommend to disable any internet connection (e.g. remove
the network cable) when you install the driver under Windows
XP - the generic driver will be installed by Windows instead
if the device wizard from Windows has access to the Microsoft
3. Does the card work under Linux?
Yes. We recommend to use the ALSA driver (which you can download
to use the card under Linux. This driver has been developed
by ALSA with hardware support from our side.
4. Does the card word under BeOS?
Yes. A driver for the card has been developed by Oliver Küchemann.
You can download it on various BeOS websites or directly on
5. Does the card work under Windows ME?
Yes. The driver of Windows 95/98 can be used to get the same
functions also under Windows ME. Optionally, you can also
use the Windows 2000/XP driver (WDM) under Windows ME but
we do not recommend this.
6. Does the card support WDM? What can I do with WDM?
Yes. WDM is the new driver standard from Microsoft for Windows.
Windows 98 SE (not Windows 95 or older Windows 98 versions),
Windows ME, Windows 2000 (not Windows NT) and Windows XP support
WDM. The Windows 2000/XP driver for the card is a full WDM
driver and can be used on all WDM supporting operating systems
with the same functions.
7. Is it possible to output signals with other samplerates
than 48kHz on the digital output?
No, this is not possible. Like most consumer soundcards,
the SoundTrack Digital XG / i-Phone XG is using an AC-97 codec
that works with internal resolution of 48kHz according to
specifications from Intel & Microsoft. To keep this compatibility,
all internal operations are done with this samplerate and
this also affects the digital output. All signals you play
back via the digital output are resampled on-the-fly to 48kHz.
8. 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
9. Can I record to MD with this card? I heard that MD
works with 44.1kHz.
Yes, MD works with 44.1kHz. This seems to be a problem as
the SoundTrack Digital XG / i-Phone XG sends all signals with
48kHz, but don't worry: all modern MD recorders and also most
older models have a built in SRC function (sample-rate-conversion)
that changes the 48kHz to 44.1kHz. The resulting change in
the signal quality is much lower compared to the compression
used for MD so this is no practical limitation at all. Some
older MD-recorders do not have a SRC function so please check
this in the documentation for your MD recorder.
10. Can I output AC-3 signals with this card?
Yes. You need a software that supports the playback of AC-3
streams (e.g. PowerDVD 2.55 and newer) that is compatible
with the Yamaha 7x4 chipset. Under Windows 2000 you need to
install at least Service Pack 2 and possibly an update for
your DVD player software.
11. Is it possible to install this card in a system with
onboard-sound or another soundcard?
Usually yes. As long as the other soundchip does not use
a Yamaha 7xx chipset, there should be no problems. You should
make sure that both devices do not share their IRQ. One exception
are mainboards with nVidia chipset. We recommend to disable
all onboar audio functions on such mainboards or you might
get a conflict with the game port of the XG card (not serious
as long as you do not use the game port).
12. Is it possible to record bit-identical signals on
the digital input?
Yes! The hardware revision that is available internationally
supports this with the WDM driver and the latest Windows 9x/Me
driver (revision 2013) when you record with 44.1 or 48kHz.
Older drivers do not support this function and resample incoming
signals on-the-fly to 48kHz as other consumer soundcards with
a digital input.
13. Does this card support S/PDIF?
Yes. The optical and coaxial digital I/O connectors on the
XG DB I pcb are sending / receiving S/PDIF signals.
14. What is the difference between the YMF744 and YMF754
chip? I heard there are different hardware revisions of this
Yes, there are different revisions. The YMF754 replaced the
YMF744 and it was no longer possible for Hoontech to produce
cards with the YMF744. The main difference between these chips
is the power consumption so there is no real practical difference
between the chips for most applications.
15. What is the difference between the 'normal' XG and
i-Phone XG cards?
The i-Phone XG card adds a special connector for a high quality
headset (included) that is perfectly optimized for internet
phone and speech recognition applications. This microphone
input is optimized for speech and the i-Phone card also adds
a special circuit to avoid feedback with phone applications.
All other functions are identical, including the drivers.
16. Are there any known incompatibilities with certain
We are aware of problems with the EPoX 8KTA3/8KTA3+ mainboard
(and the identical ENMIC 8TTX/8TTX+). We recommend not to
use this mainboard. It is not possible to use the XG card
under Windows 95/98 when this mainboard with the VIA KT133A
chipset is used. Under Windows 98SE/ME/2000/XP, installation
is only possible with the WDM drivers but the operation my
affect stability. EPoX confirmed this problem caused by a
'timing difference' between the YMF7x4 chipset of the XG card
and the 8KTA3/8KTA3+. Our own tests also showed other compatibility
issues with this mainboard. ENMIC confirmed to us that there
are known issues with other sound- and audiocards on this
board. Other mainboards based on the same VIA KT133A chipset
are not affected. Also other EPoX and ENMIC boards did not
show similar problems (although some only work stable with
the XG cards after loading the setup defaults in BIOS).
software and usage related topics
1. I am using the card under Windows NT 4.0 but there
is no support for the digital input.
Please install revision 1227 of the NT 4.0 driver or newer.
You can find updated drivers on our download page.
2. On my system, the internal Aux and Video inputs cannot
be controlled (Windows 9x/Me).
This is a known issue with older driver versions. Please
install at least revision 2008 for Windows 9x/Me to use these
3. What is the pin-layout of the Aux and Video inputs?
From left to right: R G G L (right, ground, ground, left).
Please note that since hardware revision A2 (printed on the
card), the Video input has just three pins (R, G, L).
4. I want to output AC-3 signals when watching DVDs. Do
I need to connect the DVD-ROM drive digitally with the soundcard?
No. The signal is transfered by the DVD player software via
the normal DVD-ROM data cable (IDE, SCSI). A connection to
the souncard is not needed.
5. 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 card?
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!
6. I want to use a game that supports A3D. Can I use it
with the XG card?
Yes. The SoundTrack Digital XG / i-Phone XG supports the
A3D 1.0 standard under Windows 9x/Me.
7. I want to use a game that supports EAX. Can I use it
with the XG card?
Yes. The SoundTrack Digital XG / i-Phone XG supports the
EAX standard (1.0 / 2.0 since revision 2013 of the driver)
under Windows 9x/Me.
8. I have problems recording signals from the digital
input. I can hear them and I have selected 'DigitalIn' for
recording but the WAV-file is empty.
Please note that you cannot record signals which have are
copy protected by SCMS (serial copy managment system). This
has been implemented by Yamaha to prevent users to make unlimited
number of 1:1 copies of such signals. All drivers for Windows
9x/Me/NT/2000/XP since revision 2008 do not allow you to record
signals with SCMS copy protection. You can select 'StereoOut'
as record source via the Windows mixer (which would result
in some quality loss, however).
9. Can you recommend an editing software for the Yamaha
XG synthesizer on the card?
The shareware apps XG-Edit
are working very well with the card. Also many popular sequencers
such as Cakewalk have special functions to support Yamaha's
10. The software YStation32 from the installation CD
that came with the card does not work under Windows 2000/XP.
That is correct, as the software was designed for Windows
95/98 originally. You can use the normal Windows mixer (we
recommend that for Windows 9x/Me as well) to control the card
and most popluar audio applications will work fine with the
card to record / playback audio or MIDI.
11. I get a 'file not found' error message when Windows
2000 or Windows XP auto-detects the XG card. What should I
do? I can't find the file!
Our Windows 2000/XP drivers are updating the drivers that
are already supplied with Windows 2000/XP by Microsoft. Unlike
many other drivers, you do not install them via the PnP auto
detection (because Windows already has built-in support for
YMF7x4 based cards) but simply by launching SETUP.EXE. All
files are installed automatically now. If you use Windows
XP, you must disable any automatic internet connection (e.g.
unplug the network cable) while you install the driver!
12. I want to download the Windows 2000/XP drivers and
there are two versions (YMF744 / YMF754). Which one is correct?
The main chip on the SoundTrack Digital XG is either a YMF744
or YMF754. You can check that by looking on the card itself
inside your PC to determine which version you have (just check
the number that is printed on the largest chip on the card).
This information is also printed on the retail box and on
the cover of the printed manual. All SoundTrack i-Phone Digital
XG cards use the YMF754 chip.
