I made me 10 months ago with the help of this device and an upstream automatic Ligawo HDMI mini switcher a beautiful automatic Umschaltlösung. The picture from the satellite receiver, Blu-ray players and Apple TV3 always comes on the LCD TV, the sound (stereo times, times 5.1 Surround) always has an audio projector Canton DM-90. My model which has only one digital input, selectable RCA or Toslink. The Audio Extractor are now further the sound via Toslink and everything is how it should sound. Until now, the sound only twice away. Short disconnecting the power supply came to the rescue. Reason may have been to hectic switching the upstream switch. Conclusion: Is the money worth it.
