I ordered the 2.1 cables too and they should be here tomorrow. Samsung contacted me yesterday and said they are sending me a replacement Q80R tv. I don't know how the same tv will change anything unless they've updated it but we will see. I'll post my results.
I doubt a new TV is going to solve anything. Just talking to someone at work regarding this issue and he has a Sony TV and Sonos soundbar and he is having the same issue.
He think the Dolby processing between the TV Soundbar has a very slight delay. Let me know how you get on with the new TV.
That's exacly what it is. I agree it is the tv's processing since it only happens to devices plugged into the tv's HDMI ports and only when switched to dolby digital or dolby digital +. PCM is fine but who wants to settle for stereo sound when purchasing such a nice set up. Video quality on this tv is top notch if only the sound would match the video. I highly doubt a different tv of the same model ans software is going to fix it either and I expressed that to samsung but they said "try the new one and if it's the same don't worry because it will be under warranty too". So I'm not sure what their next step would be. They already offered money back but thats not what im looking for. I just want a set up that works.
