Appendix D: Specifications390In practice, the bandwidth used when an audio device connects to atarget is higher due to the keyboard and video data consumed whenopening and using an audio application on the target.A general recommendation is to have at least a 1.5MB connection beforerunning playback and capture.However, high video-content, full-color connections using high-targetscreen resolutions consume much more bandwidth and impact thequality of the audio considerably.To help mitigate quality degeneration, there are a number ofrecommended client settings that reduce the impact of video on audioquality at lower bandwidths: Connect audio playback at the lower quality formats. The impact ofvideo consuming bandwidth is much less notable at 11k connectionsthan at 44k Set the connection speed under Connection Properties to a valuethat best matches the client to server connection Under Connection Properties, set the color depth to as low a valueas possible. Reducing the color depth to 8 bit color considerablyreduces the bandwidth consumed Set Smoothing, to High. This will improve the appearance of thetarget video by reducing displayed video noise Under Video settings, set the Noise Filter to its highest setting of 7(highest value) so less bandwidth is used for target screen changesAudio in a Mac EnvironmentFollowing are known issues in a Mac ® environment. On Mac clients, only one playback device is listed on the ConnectAudio panel when accessing the device through the Virtual KVMClient (VKC). The device listed is the default and is displayed on theConnect Audio panel as Java Sound Audio Engine. Using audio on a Mac target through Skype ® may cause the audio tobe corrupted.Number of Supported Audio/Virtual Media and SmartcardConnectionsFollowing are the number of simultaneous Audio/Virtual Media andSmartcard connections that can be made from a client to a target: 1 smartcard 1 virtual media 1 Smartcard and 1 virtual media 2 virtual media
