PCX422HR – Support

DISCONTINUED PRODUCT – END OF MAINTENANCE: June 2019

PCX422HR is a sound card with on-board processing mainly designed to be used with software applications based on Digigram proprietary driver APIs (Application Programming Interface) under Windows. The Digigram SDK  (Software Development Kit) allows the control of all the on-board features (MPEG, PCM, mixing, time-scaling, cross-fades, timed-functions, EQ, Maximizer,…)

The card can also be used as a standard linear PCM sound card through standard driver interfaces: WDM kernel streaming, DirectSound, Wasapi, ASIO, and Alsa for Linux.

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 paremeters (clock, synchro, input type selection, gains, vu-meters, monitoring, input SRC, EQ)

Supported Windows flavours
XP, Vista, 7, 8, 10, 2003 Server, 2008 Server, 2012 Server, 32-bit and 64-bit versions.

Important installation note
Under Windows 7 and Windows 8, the following error message may be displayed during the installation of the HR Runtime package:
“Windows cannot verify the digital signature of the driver required for this device….. (Code 52)”.
This error is due to a bug of Windows 7 and Windows 8 in the support of driver signatures. This error is fixed in recent Windows updates.
To fix it, it is necessary to:
1) apply the recent Windows updates. This fixes the “Code 52” error.
2) apply the following Microsoft Hotfix. This removes the remaining “Untrusted publisher” dialog box appearing when installing the driver.

Once this is done, HR Runtime can be installed correctly.

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 issue on 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 problem on recent HP motherboard not compatible with the PCIe bridge used on the cards. This has been fixed by HP with a BIOS update available on support.hp.com./

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

Sound cards

Which Linux Distribution are supported for sound cards ?

LoLa soundcards and multichannels VX/PCX series are supported on every Linux distribution, as the ALSA driver is part of the kernel.

The stereo VX and PCX stereo cards have precompiled version for Debian, Ubunutu, CentOs, Fedora and OpenSuse based distributions. For the LX series the following distributions are supported : Ubuntu LTS / Debian LTS / CentOS 7.

For other Linux distributions, we propose a service for providing an adequate compiled and installable driver package. UAx and Cancun series will work on every linux distribution.

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 update which require a new driver.
