  1. Soundbar turns off when no sound for 10 minutes.

    Its a HUGE problem. My xbox is connected through soundbar to TV, so if i browse web on xbox silently (no sounds), after 10 min not only soundbar will turn off but i will loose picture as well (tv screen goes black).

    Soundbar manufacturers are retards.

  2. I have a LP-9 Element sound bar when I pause a show in just about a minute the sound bar shuts down and i have to turn it back on to get my sound back. Just wondering if there’s a remedy for this problem?
