Trying to connect my TiVo and Home Theatre to new TV

[Alwaysaram]

I have just bought a new Panasonic Viera TV TX-48AS640, I am trying to connect my Virgin TV TiVo Box and Sony DAV-TZ140 to it. I have high speed HDMI from TiVo to TV (port 1) and high speed HDMI from Sony to TV (port 2, ARC). I cannot get any audio through home theatre speakers when watching TV channels through TiVo box. Could do with some help please!!

ARC is not automatically activated so you have to turn it on. Check the TV and HTiB menus.

Thanks for your answer. I'm having a nightmare, I have now tried using the RCA cable and removed the TiVo box. Still no joy
