Dobrý den, při přepínání kanálů často zamrzne zvukový výstup na HDMI. Obvykle při přechodu na kanál z jiného multiplexu. Obraz zůstává perfektní, kvalita signálu na vstupu je 90-100%, ale přesto se ztratí zvuk. Pak pomůže jediné - vypnout a znovu zapnout celý set-top-box, pak zvuk opět naskočí. Po několika přepnutí kanálu zvuk opět zmizí. Poradíte, co s tím?
