Our old Samsung box had hard drive problems, engineer replaced with new Cisco box last Monday. Over next two days had constant problem when changing channels sound went. Turned box off switch back on sound ok until changing channel again. Switch box off and on sound back on. Every time change channel off again, rebooted box ok until next day started again. They have now replaced with another new box and after he left started to watch and everything seemed ok changing channels until last night same problem has started again. Old box never had any sound issues.

I'm sorry to hear about the TiVo acting a little strange here. I've been able to check into some of the data on the box and found nothing out of the ordinary. I have done a test on the hard drive and so far it's come back as looking really good.
Can you tell me if this is something that is still ongoing?
This problem continued until Virgin changed box again, this time fitted a Samsung Tivo box and it works fine. All wired up exactly the same but no sound loss when changing channels. The Ciscus box actually done it why the engineer was on site, somewhere there is a fault on channel change as when sound did go you could get it back by either switching off and on the Tivo box or the TV or the Amp. As long as there was a break in the circuit the sound came back. As I said before never a problem until Ciscus box fitted and no longer a problem now I have a Samsung box.
