You can configure audio through the Policies node of the Delivery
Services Console. You control the settings for the audio features through the
following Citrix User Policy settings:
- Audio quality
- Client audio redirection
- Client microphone redirection
- Audio redirection bandwidth limit
- Audio redirection bandwidth limit percent
To set audio quality
Generally, higher sound quality requires more bandwidth and greater
server CPU utilization. You can use sound compression to balance sound quality
and overall session performance. Use policy settings to configure the
compression levels you want to apply to sound files.
Consider creating separate policies for groups of dial-up users and
for those who connect over a LAN. Over dial-up connections, where bandwidth
typically is limited, users likely care more about download speed than sound
quality. For such users, create a policy for dial-up connections that applies
high compression levels to sound and another for LAN connections that applies
lower compression levels.

To disable speakers
You can allow users to receive audio from an application on a server
through speakers or other sound devices, such as headphones, on their client
devices. Client audio mapping can cause excessive load on the servers and the

To activate user device microphones
You can allow users to record audio using input devices such as
microphones on the user device. To record audio, the user device needs either a
built-in microphone or a device that can be plugged into the microphone jack.

For security, users are alerted when servers that are not trusted by
their user devices try to access microphones. Users can choose to accept or not
accept access. Users can disable the alert on the Citrix online plug-in.

To set audio redirection bandwidth limits
You can set limits on the allowed bandwidth in kilobits for playing
and recording audio. Use the
Audio redirection bandwidth limit setting to
identify a specific maximum kilobit per second bandwidth for a session. Use the
Audio redirection bandwidth limit percent to
identify the maximum percentage of the total available bandwidth to be used. If
both settings are configured, the one with the lowest bandwidth limit is used.
