7.4.3 Card availability under ASIO
If the ASIO driver for the card has been installed (option to be selected during the installation
procedure), then the card must be detected and displayed in the ASIO control panel.
This control panel can be started from the ASIO application to select the appropriate audio
devices.
All cards present must be listed in the "ACTIVE CARDS GROUP" selection list.

7.5 Adjusting the internal latency of the card

The following describes advanced settings that may impact the proper functioning of data
exchanges between the card and the PC. It is recommended that you do not change these settings.
The internal latency of the card is determined by the duration of sample buffers the card exchanges
with the PC for playback and recording audio streams. By default, this duration is 32 sampling clock
periods (0.67ms at 48 kHz).
The lower the internal latency, the lower the global latency of the card. However, a very low latency
may lead to "choppy" audio on slow PCs. In this case it is necessary to increase the internal latency.
The internal latency of each ALP card can be changed by selecting the properties of the card, from
the Windows Device Manager:
Right click on the ALP card, and select Properties, Advanced.
The following window is displayed:
