Version 6.50f004 Release notes

WARNING

Audio dropouts can be experienced on some PCs under Windows 7 with discontinued cards supported by npRuntime. This may be due to other devices in the PC (see procedure in the release notes), but also to the architecture of these discontinued cards.

We strongly recommend to test first the system before deploying it.

 

This driver package installs the Digigram np driver as well as the Wave driver for the cards.

 

WARNING

Audio dropouts can be experienced on some PCs under Windows 7 with discontinued cards supported by np Runtime. This may be due to other devices in the PC (see procedure below), but also to the architecture of these discontinued cards.

We strongly recommend to test first the system before deploying it.

In case audio dropout are experienced, here is a procedure that may help get rid of them.

 

Run DPC Latency checker. This is a free application developped by Thesycon.

 

after at least one minute, in case the bargraph is green, there is no potential issue. In case the bargraph is yellow and/or red, the computer most likely produces dropouts and artifacts.

 

It is possible to identify the source of the problem, by running the software application LatencyMon from Respledence.

 

LatencyMon displays the list of drivers (drivers tab). You can sort the list by highest execution time (double click on ‘Highest excution (ms)’ column header).

 

All drivers which highest execution time is equal or able 1ms are potential sources of the dropouts.

 

You can then deactivate the devices associated to these drivers from the Device Manager. Be careful, some components should not be deactivated as they are essential to the system.
