I have the Q10 pro with the 2.1 update..this was an issue to me before the update as well.
the update made google play finally work thx for that..I have Sony Crackle, Amazon Prime, Netflix, these apps broadcast audio in 5.1 Dolby Digital through Xfinity Comcast and my Samsung smart tv but when I run the same apps through the Q10 menu the sound is PCM Stereo (any movie or show). I select RAW or PCM in settings makes no difference.. either through the HDMI or the Optical cable to the AV amp
I looked through all the q 10's settings I didn't see anything, I also looked into each apps settings as well , nothing there either..
the Q 10 plays all the DD sound on files Like .TS, AVI, MKV etc....5.1 or 7.1 no probs..
I don't use the kodi app to compare with..
any Ideas ? maybe I'm missing something simple....thx for any suggestions, I will post any outcome....cheers!
