Advertisements One thing you need to realize... the sounds TiVo makes are PCM Stereo, the audio in most TV shows will be Dolby Digital. So even when this is working correctly you will NEVER hear the TiVo sounds when watching a show. It's simply not possible for them to mix their PCM sounds into the DD audio from the show. You should be able to hear them in the menus, but your receiver and TiVo have to renegotiate the connection to switch from DD to PCM every time, which can have a delay and if you force it too quickly, like by hitting the TiVo button a bunch of times, you can confuse that negotiation. I'm not saying your receiver isn’t having some issues, but some behavior modification and expectations have to be changed if you're coming from no receiver. The only way to make it keep working the way it did before is to go into the TiVo settings and set it to only output PCM Stereo. But then you're losing all the benefits of having a receiver in the first place.
