Secure Global Desktop Enhancement Module Does Not Work in PulseAudio Mode on Linux Systems (Doc ID 2040936.1)

Last updated on AUGUST 12, 2015

Applies to:

Oracle Secure Global Desktop - Version 5.2 to 5.2 [Release 5.0]
Information in this document applies to any platform.

Symptoms

Secure Global Desktop (SGD) administrators may receive reports that applications provisioned with audio configured to use PulseAudio on Oracle Linux 6 application servers do not work as expected--no sound is emitted--after installation of the SGD Enhancement Module (EM) for 5.2.  In this scenario, updating the configuration to SGD EM to use OSS Audio will allow sound to correctly work within the provisioned applications.

Verification

The SGD Administrator may verify this unique scenario by enabling diagnostic logging per:  http://docs.oracle.com/cd/E51728_01/E51731/html/audio.html#audio-unix-logging, the generated logs may show entries like the following:

ex.: /opt/tta_tem/var/log/sgdaudioPID.log
