No sound device in Solaris 11 running in Parallels (MacBook Pro)

I'm new to Solaris. I was able to installed Solaris 11 running GNOME. I tried to detect sound/audio but the message given that "No volume control GStreamer plugins and/or devices found". There is no dev/audio but there are audio drivers such as gstreamer installed when I checked using Solaris Package Manager. Even when I search using keyword in Package Manager "audio", the audio drivers are installed. How do I enable the audio driver so that I can listen to music in Solaris. Thanks.

I managed to fix this. I just add the sound option in Parallels - it works. Solaris was able to detect the sound driver.
