Right from the start, when I purchased my Samsung N5300 several months ago it dropped the audio from my Samsung HW-N400/ZA after 4 to 6 hours of use. The only way to reset it was to maneuver through the menus and run the Soundtest in the N5300's support menu. It was kind of annoying but it fixed it every time for another 4 - 6 hours of use. My N5300 shipped with firmware 1204 so I updated it to 1251, but the issue continued. I updated to v1260 several weeks later, but it offered no resolution to the dropping soundbar.
I'm pleased to report that firmware v1270.7 that was released earlier this week completely resolves the audio dropping out with my HW-N400 soundbar. Works like a champ now with no dropouts!
