No Audio in F22

[Stephen Morris]

Hi,
     I have installed F22 from scratch via the live dvd and even though 
I have pulseaudio installed and configured via the multimedia interface 
in system settings in KDE I am unable to get F22 to play any sounds at 
all, plus I don't have a speaker icon in the system tray.
     I had no issues with audio in F21 on the same hardware, nor do I 
have any issues on this hardware under windows.
     I am using the onboard 7.1 surround sound audio chip on the 
motherboard.
     Does anyone have any ideas on what I can look at to work out why 
there is no sound?

regards,
Steve
