SysAudio reserves the registry category KSCATEGORY_AUDIO_DEVICE exclusively for its virtual audio devices.

#VIRTUAL AUDIO SOUND DRIVER HOW TO#

The KsStudio utility in the Windows Driver Kit (WDK) is an example of an application that bypasses SysAudio and allows users to construct filter graphs manually.ДЇollowing PnP device enumeration, SysAudio takes stock of the registered audio hardware and software components in order to determine how to construct the various audio filter graphs that its clients might require.ДЄfter determining the list of filter graphs that it can build from the available hardware and software components, SysAudio registers these graphs as virtual audio devices for playback, recording, MIDI input/output, and mixing.

SysAudio's clients include DirectSound and the WDMAud system driver, which serves as the interface between WDM audio drivers and the audio-specific Microsoft Windows Multimedia APIs waveIn, waveOut, midiIn, midiOut, mixer, and aux (described in Microsoft Windows SDK documentation). The system audio driver (SysAudio) uses the available hardware and software components to determine the filter graphs to build.ДЇor more information about the system audio driver, see SysAudio System Driver.

Choose the same channel (Livewire In 01) in the input configuration of your encoding application. ChooseВ IPВ DriverВ channel 1 as the Output Device in the Audio Processor instance of X/2 (Livewire Out 01). TheВ IPВ DriverВ will show up in the Windows sound card list just like any other sound card. Any channel can be used, however, you can not duplicate a channel. In this example we are using Livewire channel 1 as a 'virtual audio cable' to loop the Source (output) to the Destination (input). Use the same channel numbers on the 'Destinations' side that are in the corresponding 'Sources' side. Add the Destination (the input to the driver) channel numbers. Once installed and licensed, you need to enable the required channels via the checkboxes on the left side Sources (the outputs of the driver). The installation of the streaming software will not prompt you to reboot however, you need to reboot one final time for the driver to work correctly. Once complete, you MUST reboot one more time to allow the driver to recognize this new license.

This process adds a license for the Axia IP-Audio Driver.

#VIRTUAL AUDIO SOUND DRIVER INSTALL#

Complete the steps of the install and reboot.ДЇollow the instructions for installing and licensing the software.

When you reach the point of the install where it is asking you for a key, proceed past it without entering any information.

Follow all instructions and pre-requisites for installing the driver.

Download the most recent version of the Axia IP-Audio Driver from the Telos website.

Using the Axia IP-Audio driver in the place of VACД®ach X/2 or A/XE license will automatically license four channels of the Axia IP driver, which you can configure to work just like VAC. You can continue to use VAC for this purpose however, you would need to obtain a version from them directly to work with your Operating system. VAC was supplied, free of charge, under a special arrangement with the original maker of the software, Eugene (Evgenii) Muzychenko, an independent software developer and is still sold today on his website.
