I have a new bug with the box and I dont know if she is the problem ... That is boring me

Yesterday, I updated my hisense xt910 to new g1107 firmware and now hdmi audio raw output with the box is not working, my audio system doesnt detect dolby or dts codec (it is capable to decode)
The box is connected to the tv with hdmi and the tv to the audio system with toslink optical cable (and it is set to raw also)
But I tested another device set on raw output and it is working fine
Between, I didnt had this problem with the previous tv firmware and what is boring me most is that updates take long time to come ...
