Re-Enabling Disabled Audio Devices on Remote PC Endpoints
– закричала она, Ричард приподнялся на локте. – Ну-ка, где прячут Эпонину и Элли? Периоды долгого молчания прерывались потоками явно нелогичных вопросов. Кэти глубоко вздохнула и улыбнулась.
Troubleshooting ICA Client Audio Issues – Applicable Products
Set the Policy to Low , Medium, or High the definitions are explained in the following section. The console or tool used to complete this depends on whether or not your network environment includes Microsoft Active Directory and whether or not you have the appropriate permissions to manage Group Policy Objects GPOs. Apply the filters you want the policy to be applied to. If using a XenApp console make sure the policy is enabled and prioritized to the desired level.
Use the projected figures for each level of sound quality to calculate the bandwidth potentially consumed in connections to specific servers. For example, if 25 users record at Medium on one server, the bandwidth used in the connections to that server is over 52, bytes per second. Bandwidth is consumed only while audio is recording or playing. If both occur at the same time, the bandwidth consumption is doubled. Low – for low speed connections for low-bandwidth connections. Sounds sent to the client are compressed up to 16 Kbps.
This compression results in a significant decrease in the quality of the sound but allows reasonable performance for a low-bandwidth connection. With both audio playback and recording, total bandwidth consumption is 22 Kbps at maximum.
Medium – optimized for speech for most LAN-based connections. Sounds sent to the client are compressed up to 64 Kbps. With both audio playback and recording, total bandwidth consumption is High – high definition audio for connections where bandwidth is plentiful and sound quality is important. When connecting through an ICA session, audio output sounds distorted or choppy. RDP sessions do not exhibit this same distorted audio output. The quality of audio that each session receives depends as much on the network connection as it does on the XenApp environment configuration.
There a few different options for configuring audio bandwidth limits in your session and each of these settings plays an important role in the actual audio output quality that your users hear. There are three audio quality options High, Medium, and Low that can be configured for any ICA session, and each setting sets a determined amount of bandwidth for the audio throughput within the session. The default audio quality for any XenApp server is set to medium quality, which could limit the audio stream and affect the actual audio output sound.
Setting the audio quality option to High increases the bandwidth and should give you the best audio quality possible for your ICA session. There are different methods to configure the audio quality options for your ICA sessions, following are instructions and explanations for each:. Click Apply to save this setting. The Citrix policy for audio is for specifically setting a lower audio quality than the server default value.
So, if you have the server set to high audio and you have a group of users that do not require this much bandwidth for audio, then you would create an Audio policy restricting this group of users. Secure Director deployment. Configure with Citrix Analytics for Performance.

You can configure and add the following Citrix policy settings to a policy that optimizes HDX audio features. For usage details plus relationships and dependencies with other policy settings, see Audio policy settings and Bandwidth policy settings and Multi-stream connections policy settings.
Adaptive audio optimizes settings for your environment and replaces obsolete audio compression formats to provide an excellent user experience. Adaptive audio is enabled by default. To disable adaptive audio, see Audio policy settings.
Therefore, sometimes it might be preferable to use TCP transport. In general, higher sound quality consumes more bandwidth and server CPU utilization by sending more audio data to user devices. Sound compression allows you to balance sound quality against overall session performance; use Citrix policy settings to configure the compression levels to apply to sound files.
By default, the Audio quality policy setting is set to High – high definition audio when TCP transport is used. The policy is set to Medium – optimized-for-speech when UDP transport recommended is used. The High Definition audio setting provides high fidelity stereo audio, but consumes more bandwidth than other quality settings. Do not use this audio quality for non-optimized voice chat or video chat applications such as softphones.
The reason being that it might introduce latency into the audio path that is not suitable for real-time communications. We recommend the optimized for speech policy setting for real-time audio, regardless of the selected transport protocol.
When the bandwidth is limited, for example satellite or dial-up connections, reducing audio quality to Low consumes the least possible bandwidth. In this situation, create separate policies for users on low-bandwidth connections so that users on high-bandwidth connections are not adversely impacted. For setting details, see Audio policy settings. Remember to enable Client audio settings on the user device.
To allow users to receive audio from an application on a server through speakers or other sound devices on the user device, leave the Client audio redirection setting at Allowed.
This is the default. Client audio mapping puts extra load on the servers and the network. However, prohibiting client audio redirection disables all HDX audio functionality. Remember to enable client audio settings on the user device.
To allow users to record audio using input devices such as microphones on the user device, leave the Client microphone redirection setting at its default Allowed. Users can choose to accept or reject access before using the microphone.
Users can disable this alert on Citrix Workspace app. The Audio Plug N Play policy setting allows or prevents the use of multiple audio devices to record and play sound. This setting is Enabled by default. Audio Plug N Play enables audio devices to be recognized. The devices are recognized even if they are not plugged in until after the user session has started.
The Audio redirection bandwidth limit policy setting specifies the maximum bandwidth in kilobits per second for a playing and recording audio in a session. The Audio redirection bandwidth limit percent setting specifies the maximum bandwidth for audio redirection as a percentage of the total available bandwidth.
By default, zero no maximum is specified for both settings. If both settings are configured, the one with the lowest bandwidth limit is used. For setting details, see Bandwidth policy settings. UDP allows for packet loss without retransmission, ensuring that no latency is added on connections with high packet loss.
This helps avoid Citrix Workspace app clients requesting open UDP connections or triggering unwanted Citrix Workspace app client firewall configuration dialog windows to appear.
As an Administrator, if you do not have control on endpoint devices to make these changes, use the default. For example, for bring your own devices or home computers. Users in audio or video conferences might hear an echo. Echoes usually occur when speakers and microphones are too close to each other. For that reason, we recommend the use of headsets for audio and video conferences.
HDX provides an echo cancellation option enabled by default that minimizes any echo. For XenApp 7. In XenApp version 6. When using low quality as the audio setting, the compression of the already compressed MP3 file causes some audio data loss. To prevent this, change the audio quality setting to Medium or High for the connection. Citrix Product Documentation – Optimize audio features.
