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 on-board features: PCM audio mixing, cross-fades, timed-based and event-based functions. VX222e card does feature on-board support of MPEG audio and time-scaling.

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 card’s parameters (clock, synchro, input type selection, gains, vu-meters, monitoring, input SRC, EQ)

Supported operating systems

• Windows 10, Windows Server 2016
  No support is provided for systems running under Windows OS versions which mainstream support from Microsoft has ended.
• Linux
  For cards produced before 2017, the Alsa driver is included in the Linux kernel.
  For cards produced as of 2017, a driver package is available on request, or on this GitHub link.

Important installation notes
Installation under Windows 10 and Windows Server
In case a previous HR Runtime version is already installed, it is necessary to uninstall it prior to installing the most recent one.

> Hardware change (March 2017)
Due to the obsolescence of some components used on all the Digigram stereo PCI Express sound cards, we have made some hardware modifications on these cards. These modifications guarantee the same features, the same specifications, and the same performances. In this regard, the name and the product reference remain unchanged. The ID  for the technical status of the card is increased. It is visible on the sticker on the back of the card (IS=).

It is necessary to install HR Runtime version 1.76d001 to be able to support these modifications under Windows. Note that this new HR Runtime also supports the previous non-updated cards.*
For cards produced as of 2017, a Linux driver package is available on request. Please click on the link “contact the support team” on top of this WEB page.

> Installation error message under Windows 7 and Windows 8 (no longer supported)
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.
