Greg: Thank you for sharing your experience with the Samsung TU8000 TV. I am sorry you are experiencing issues with your sound cutting out and were not able to resolve it with Customer Support. If the audio drops out issue is happening when connected via HDMI, the HDMI cable is most likely the cause. We recommend you replace the HDMI cable with a High-Speed cable with Ethernet Channel, labeled as HEC or HEAC on the cable. If this does not help, we ask that you contact us again for additional troubleshooting or assistance with setting up a service appointment. 1-800-SAMSUNG (ask for TVs), available 8AM -12AM EST, 7 days a week Or visit us on the Samsung website and click on the ‘Support’ link in the upper right corner of the homepage for: 1) Contact Us Options (LiveChat, Remote Support, Facebook, Twitter) 2) Product Support 3) Manuals and Downloads 4) Warranty Info 5) Product Registration: Registering your product gives you access to easy warranty support, convenient opt-in to special promos and offers, faster troubleshooting and service, and quick notification of system updates 6) Samsung Community: A great resource for getting help from Samsung moderators and customers and more 7) …and more product, repair, order, and care options ~ Samsung Solutions
