Since the new software update I am experiencing occasional no sound after changing channels. It happens more frequently on HD channels. I'm also getting this on the programme guide.
Putting the Tivo box into and out of standby cures it. As does removing and replacing the HDMI connection.
We've had the Tivo box changed to no affect.
Is anyone else getting this?
I'm sure the Tivo HDMI driver software has been updated.
This is happening to me as well. Problem started immediately after the upgrade. It also happens when I exit a recording using the "arrow left" key. Usually I can get the audio to return by hitting the "slow" key twice, but sometimes that doesn't work so I have to put the box into standby and turn back on again.
I too am having the same problem. I have loss of sound when changing channels, mainly on HD channels but also some standard channels. I've had an engineer out who has gave me a new TiVo box but still the same problem so I've lost all my recorded programmes for nothing. The engineer could find nothing wrong with the box or my TV as everything else I have has sound . the TiVo box worked with the TV he brought with him but not on mine or through my amp. It keeps loosing sound when channel is changed. He said he has never heard of the problem before. Maybe the update doesn't agree with certain makes of TV.
