I have had the SA 8300HDC for a week now and just got the chance to tinker with it. I am using HDMI for the hookup with digital out for the audio. I was reading that the receiver defaults to 2 channel and that I would need to go into settings to switch it to Dolby Digital. That's the problem..The only option I have under audio is...narrow,wide or normal,nothing else. I hooked up the receiver with components and did a reboot and I still don't have any audio options. The cable company is privately owned by the city I live in and was wondering if they may have something to do with it.Any input would be greatly appreciated.
