PRODUCT PAGE

VX820e is a linear PCM sound card designed to be used through the following standard driver interfaces: WDM kernel streaming, DirectSound, WASAPI, ASIO, and Alsa for Linux.
It can also be used with software applications based on Digigram proprietary Application Programming Interfaces (APIs) under Windows operating systems, so as to benefit from the available on­board features: PCM audio mixing, cross­fades, timed­based and event­based functions. VX820e card does feature on­board support of MPEG audio and time­scaling.

The “HR Runtime” package allows installing the following components:

  • WDM DirectSound driver
  • ASIO driver with its ASIO control panel (CPL)
  • Legacy Wave MME driver
  • Digigram Hardware Settings (DHS) application, which allows setting the cards parameters (clock, synchro, input type selection, gains, vu­meters, monitoring, input SRC, EQ)

Supported operating systems 

  • Windows 7, 8, 10, 2003/2008/2012/2016 Server, 32-bit and 64-bit versions.
    No support is provided for older Windows OS. Recent versions of cards are not supported for OS older than Windows Seven.
  • Linux
    Alsa driver is included in the Linux kernel.

Q&A

VX/PCX

How can I adjust my VX/PCX audio levels

When the driver is installed, the DHS software (Digigram Hardware Settings" is installed. Just run that software to have access to the IN/OUT level adjustments.

How to select the AES input ?

In the DHS you have to set the clock to AES/EBU Sync to be able to select the AES input.

I am facing a BSOD when using my VX sound card

We face issues on the HP computer with the DMA management. To avoid BSOD, you have to disable the DMA protection in the BIOS

My recent HP computer do not boot with a VX, PCX or LX-MADI sound card

We identified that some recent Hewlett-Packard computers (HP Z1 G6, HP ProDesk 400 G7, HP Elitedesk 800 G6, HP ProDesk 600 G6 Microtower PC, HP Z2 G8 Tower Workstation, HP ProLiant DL360, HP Proliant DL380) don't boot with VX, PCX and LX-MADI PCIe sound cards. This is due to a problem with the recent HP motherboard incompatible with the PCIe bridge used on the cards. HP has fixed this with a BIOS update available on support.hp.com./

If you encounter similar problems with other HP references, kindly check the support.hp.com  website for individual BIOS updates since there is no constant firmware available for all of these models.

My sound card is not detected by Windows

Make sure that you downloaded the lasted driver on our website. Indeed, from time to time we have to make component updates that require a new driver.
