I've only had my Tivo box for just over a month and ever since it was set up I've been having audio problems intermittently. The audio randomly starts going all fuzzy and duplicated, its hard to explain. It sounds like a digital noise where the audio is vibrating and just glitchy. Lasts for about 10-20 seconds and then it's fine.
Sometimes it won't occur for days but then will happen several times in an hour.
I'll try and record a video of it to post up if that'll help.
Could it be a problem with the HDMI Lead? I'm using the one that came with the set.
