I’ve installed the control panel software on my Windows Vista PC, but it doesn’t work. How do I fix this?

Some Windows Vista versions mistakenly associate a Prism Sound USB audio device with Windows’ built-in UAC1 driver rather than the Prism Sound UAC2 driver, even though the UAC2 driver has been installed correctly.

To fix this, you must correct the association manually using the Windows Device Manager:

  1. Select ‘Control Panel’ from the Windows Start button
  2. Select ‘System’
  3. Select ‘Device Manager’
  4. Scroll down to the list of ‘Sound, video and game controllers’ and expand it
  5. You should see an entry for ‘Prism Sound [name] USB Audio interface’. Double click this entry to open the ‘Properties’ box
  6. Select the ‘Driver’ tab
  7. Click the ‘Update Driver…’ button
  8. Select ‘Browse my computer for driver software’, followed by ‘Let me pick from a list of device drivers on my computer’
  9. Highlight the ‘Prism Sound [name] USB Audio interface’ and click the ‘Next’ button.

Windows will now associate the Prism Sound USB Audio driver correctly.

Which operating system do I need?

For Windows, you’ll need Vista or later.

Operation under Windows 8, 8.1, 10 and 11 have been tested. It’s always best to use the most recent drivers and firmware, these are necessary for Windows 8, 8.1, 10 and 11. Microsoft have discontinued support for Windows 7 and we are therefore not able to fully support the use of our interfaces under it. Due to some changes in the behaviour of the WDM driver between Windows 7 and Windows11, we recommend that you use the 1.24 driver package if you are continuing to use Windows 7, and not higher versions.

For Mac, OS X 10.5 or later on an Intel platform.

Titan, Lyra and Atlas are fully compliant with Mojave and Catalina when using the recent Control Panel apps and firmware (v2.03 or higher).

There are new security settings in Mojave and higher to allow access to the Microphone and Camera (and these can be changed in Preferences/Security & Privacy/ Privacy). We have come across reports that some DAW software may need access to the microphone in order to record (from any audio input). If users are experiencing issues of this sort, where audio appears in the Prism interface but not in the DAW, it would be best to check the DAW software’s website for any further information.

How can I tell what version of firmware is in the hardware?

The Firmware version is reported in the top bar of the Control app.

If you are still running the old grey Control app, the firmware version is reported when hover the mouse over the serial number near the top of the Control app. Before you upgrade to v1.17 firmware or higher, you must upgrade the software to the black Control app, version 2.03 or higher first.
