DSP24 - FAQ answers

On this page are answers to some of the most common questions we receive about the DSP24 PCI-card.

software and usage related questions

Back to general questions (hardware, drivers & compatibility)
Forward to DSP24 specific topics



1. Can I output AC-3 signals with this card?

Yes, the hardware supports this. Currently this is supported with Intervideo WinDVD 3.x and Cyberlink PowerDVD under Windows 2000/XP.

2. What is the latency of the ASIO 2.0 driver and how can I change it?

The latency can be lowered to 2ms at 96kHz and 5ms at 44.1/48kHz since driver v6.0. Under Windows 2000 and XP, even lower settings are available. Keep in mind that stable operations with small buffer sizes require a very fast computer.

The latency depends on the selected ASIO buffer size (which can be changed under External Links > Hardware Settings > Device Setting > ASIO/MME buffer). The lower the selected buffer value, the lower the resulting latency will be. Also, if you lower the buffer size, the system requirements (CPU, low background activity, etc.) will increase.

We recommend to check the Hardware Settings dialog article in the Knowledge Base with further information on this.

3. I have read that the card is full duplex, but I can't do simultaneous record and playback with Cakewalk!

Simultaneous record and playback needs to be enabled in Cakewalk Pro Audio. In the software, go to Settings > Audio Options > Advanced and make sure Enable simultaneous record and playback is checked.

4. I am using Cubase VST 5.x and I'm getting crazy: always when I change a setting inside External Links or the mixer, the playback suddenly stops!

Make sure the menu entry Options > Active in Background is checked inside Cubase. This is a general Cubase setting and not related to the audiocards driver.

5. I am using Cubase VST 3.xx and I'm getting crazy: always when I change a setting inside External Links or the mixer, the playback suddenly stops!

Goto File > Preferences and make sure that Active in Background is checked for MIDI and Audio. This is a general Cubase setting and not related to the audiocards driver.

6. When recording or playing audio under Windows 9x/Me, I get an audible click about every 3 to 5 seconds. Is the hardware defective?

No! First of all, check the following two settings:

Make sure the 'auto-play' function for CD-ROMs is disabled. Goto Control Panel > System > Device Manager > CD-ROM and select Properties for all CD-ROM drives. Now disable Auto Insert Notification under Settings.

DMA access for your IDE HDDs must be enabled. Goto Control Panel > System > Device Manager > Disk Drives and select Properties for each IDE-HDD you have installed (an entry is typically called GENERIC IDE DISK TYPExx). Now enable DMA under Settings.

Please check these settings from time to time. Some Windows installations 'loose' the DMA and CD-ROM notification settings when you are changing certain elements in the hardware configuration or if you boot Windows in Safe Mode.

7. I can hear cracks and noise when I play my recorded audio signal! Is this a hardware problem?

In most cases this problem can be solved by changing the interrupt which has been assigned to your hardware. Check in Control-Panel > System > Device Manager > Computer > Properties if there is another hardware component using the same interrupt as the DSP24 Value (it should have its own interrupt, especially on mainboards using the VIA chipset). Except an IRQ-Holder entry, no other device should be listed with the same IRQ number. If you find such a problem, you usually have to install the DSP24 series card into a different PCI slot. On some mainboards you can change the IRQ assignment inside the BIOS of your mainboard. Check this article in our Knowledge Base about IRQ assignment.

8. The performance of my audio applications under Windows 2000/XP is not as good as under Windows 9x/Me when using Cubase VST , Cubase SX, Ableton Live, Logic Audio or Nunedo. I get too many drop-outs. What can I do?

Under Windows 2000 (not XP), goto Control Panel > System > Advanced > Performance Options and select Background services. Under Windows XP, goto Control Panel > System > Advanced > Settings > Advanced > Processor scheduling and select Background services.

9. I can hear noise when I move a window or fader on screen inside my audio application. I am using an ATI Rage 128 graphic card.

Please download and install current drivers for your graphic card and set the bit-depth to 32bit (not lower). This will reduce the system load the graphic card is causing.

10. I can hear noise when I move a window or fader on screen inside my audio application. I am using an Matrox Millenium/Mystique/G200 card.

Please download and install current drivers for your grpahic card. Inside the Matrox specific options you can find a setting called Busmastering - please disable it.

11. 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!

12. Can I use Logic SoundTrack24 under Windows 2000 or XP?

No, this is not possible if you use v4.2 of Logic SoundTrack24. This version of Logic from Emagic only works under Windows 9x/Me ... Windows 98 SE is recommended. The newer v4.8 of Logic SoundTrack24 also works under Windows 2000/XP however.

13. When using Media Player from Microsoft (or any similar software), the output is played through the 1/8" output on the card. How can I change this?

Media Player and most other programs use the wave device that is selected in Control Panel > Multimedia > Audio as prefered device for playback. Select ADSP24 Ext. 1/2 Audio Device if the signal should be played via the External Mixer. The signal will be played via the 1/8" output when you have selected ADSP24 Int. Audio Device as playback device (recommended). Some programs also allow you to select the wave device inside the application (which means that the Control Panel setting will be ignored).

14. I am not able to change the MME / ASIO / GSIF settings for the multiclient driver in the Hardware Settings dialog.

These settings are not available when the driver you are currently using does not support multiclient operation with GigaSampler-/Studio. Please update to the latest revision of the drivers to use the multiclient support.

We recommend to check the Hardware Settings dialog article in the Knowledge Base with further information on this.

15. I want to use Emagic Logic Audio 4.x Silver/Platinum/Gold under Windows 2000/XP. Does your driver support this?

Yes, however you need to use at least Logic Audio 4.8.1. If you use an older v4.x version, you can get a free update via Emagic or one of their distributors.

16. I want to use Tascam GigaSampler/-Studio under Windows 2000/XP. Does your driver support this?

Yes but you need to have at least v2.5 of GigaStudio. GigaSampler does not work under Windows 2000/XP.

17. I want to use Steinberg Cubase VST 3.72 under Windows 2000/XP. Does your driver support this?

No, but this is not a limitation of our driver. The official versions of Cubase VST 3.xx do not support Windows 2000/XP.

18. Why do I get error messages that the ASIO Multimedia test/configuration failed using Cubase VST, Cubasis VST, Cubase SX or Nuendo from Steinberg?

This test is done by the ASIO Multimedia driver from Steinberg that simulates ASIO for soundcards without ASIO support. It would disappear as soon as this driver is configured properly. However, as the DSP24 series of cards have their own ASIO driver for Windows 9x/Me/2000/XP, you don't need to run this test at all. Just select the ASIO driver (ASIO ADSP24) inside your audio software and then the ASIO Multimedia driver will no longer be used.

19. Why do I get the Windows Mixer (SNDVOL32.EXE) when calling the Internal Mixer?

From all updates released after June 2002, we are using the normal Windows Mixer instead of the older Internal Mixer application for Windows 9x/Me. You can find more information in the Internal Mixer Knowledge Base article.

20. The External Mixer only displays the Input 1/2 channels ... I am not able to control Input 3~8 - what can I do to fix this?

This happens if you have or had installed the drivers of the DSP24 Value card on your system. Please uninstall the driver with the DSP24Inf.exe utility that is inside every driver ZIP-file. Now make sure to install the correct DSP24 (not Value) driver.

You can also use this .REG file to remove the informations about the DSP24 Value from your Windows registry manually. Double click on it and then re-install the drivers.

21. External Links only displays one MIDI port. Where is the second port?

The DSP24 card only supports one MIDI input which is displayed inside External Links. The two supported outputs are not displayed in the software as the outputs are configured automatically. The input is displayed so that you can assign a specific input channel from an external box.
