HiMedia works poorly with the Bravia XR-50x90S and soundbar. Such a strange phenomenon. After connecting the Creative Stage V2.1 soundbar (HDMI ARC connector) and HiMdia to the TV (HDMI 4 extended) everything works OK, but after turning off (power off) HiMedia the sound switches to the TV speaker, and when I switch back to soundbar sound it is only silence. When I turn on HiMedia, the sound from the soundbar comes back. When I want to use only the TV and soundbar, I have to remove the HDMI cable from HiMedia, otherwise the soundbar is inactive.
Anyone advise something?
Bravia XR-50x90S is the same model as the Bravia XR 90K, only with worse speakers.

After installing MX Player Pro  (firmware 1.09, Q10 Pro) I can not see anywhere the application icon. I need to run Google Play and start MX. MX Player standard icon is visible. In firmware 1.08 everythig was OK.
