Supported on: All Citrix Workspace supported platforms
Description
Use this policy to enable and restrict the remote application or desktop's access to local audio capture devices (microphones).
Registry
HKLM
Software\Policies\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Audio Value name: EnableAudioInput
Enabled: EnableAudioInput = true,false
Disabled: EnableAudioInput = false
REG Builder
BETAConfigure the state and elements to generate .reg, PowerShell, Intune, and SCCM outputs.
These exports replicate the policy's registry effect. Editing the registry directly is not the same as applying the GPO through the management console (no gpupdate, no central reporting). Test before production; HKLM changes require administrator rights.
