REQUIREMENTS

System Requirements for Virtual Audio Cable (VAC):

Server 2008, Windows 7, Windows8/8.1, Windows10 platforms – 32-bit or 64-bit. Physical or virtualized host.

First we will download and install VAC on the host PC.


Trial version has the following limitations:

Supports up to 3 redirections and adds female voice reminder every several seconds.

Make it a standard installation:

If your system is 32bit, use the setup.exe file and if it’s 64bit, use the setup64.exe file. Click Install thru all the installation process.


After the installation is completed, VAC will add a new audio device to your system called “Line 1 – Virtual Audio Cable”
This audio device will be used to receive the audio channel and redirect it to all audio devices on the zero clients.
You can either use it as your Default audio device: simply right click and select “Set as default”,
or you can set a specific application to redirect its audio to that device.


Each zero client has an Audio device that appears on your Playback Devices console as USB Audio Device.


Open this folder :

C:\Program Files\Virtual Audio Cable

And run this application:

audiorepeater.exe




Setting up MAWi to run Virtual Audio Cable

After you’ve successfully installed Virtual Audio Cable (VAC) we can go on and set the configuration in MAWi:

Choose the Main screen from the list of monitors.



On the second field  copy this line below and paste it to the Parameters Field:

/Input:”Line 1 (Virtual Audio Cable)” /Output:”Speakers (C-Media USB Headphone” /BufferMs:50 /AutoStart

/Input – should be left without change.
/Output – Replace according to the device’s name as it appears on your system.
/BufferMs – should be left without change.
/AutoStart – To make sure it starts automatically.


To get the full name of your audio device, open the audiorepeater manually and select your
USB audio device and then copy it by pressing CTRL+C, then in the parameters field simply use
CTRL+P to paste the full name of the device after the “/Output:” section.

Finally click Save and Send and the audiorepeater app will start redirecting the sound to your zero client.

Repeat all stages above for each audio device.
