So just got my new Vizio sound bar, before this all was working fine with no issues on my 7+ year old Yamaha receiver and speaker system.
The games work fine and TV sounds fine. However inside the dashboard, the audio will cut in and out as I move around the dashboard. When going from the dashboard to a game, it may take a second or two for the audio to kick in (for example forza when it shows that arrow, it takes a bit), once it does though it works.
Any ideas what is going on? I've already powered down/unplugged it and replaced the optical wire twice.
