Audio confusion with You Tube Clips vs Movies

Hi all

set up the WD TV Live today and had a few issues (menus **bleep** to get to media after using media centre on the PC) but anyway…Got it all working, playing all the files I wanted so very happy with that but when I was testing out You Tube I had no audio. I was initially using HDMI to amp and then changed to Optical lead for audio and also changed settings ans still no audio. I then plugged in composite leads and had audio…My question is, to watch You tube with audio do I need to have the composite plugged in all the time and manually change settings each time or have I missed something??

Thanks

Mick

Most of the time, yes.
