Power with some receivers problems

I bought the audio signal from HDMI via Toslink SPDIF or to my receiver to lead me to Ligawo HDMI decoder.
With regard to the conversion and everything works fine. All Mehrkanaltonformate be correctly recognized.

Here is briefly interrupted at the music playback between tracks the Toslink / SPDIF stream. My receiver then needs about 1 second to lure back to the onset of new data stream which is always cut off the first second of the beginning of the music piece. I also have not found a way to bring the decoder to with a very low noise level to maintain the connection.
While looking film that falls not on, at individual pieces of music, it is a bit disturbing. Too bad, otherwise the instrument is highly recommended.
