Media Box => UAPP => High End stereo amp

[cch]

I purchased both Himedia Q10 pro (upgraded to Android 7, FW 2.0.4; ca. 1 TB of music on local hdd) and UAPP (3.6.5). The System connects successfully to a Devialet Expert 200 amp via USB.

Stupid question: How can i access UAPPs Settings? E.g. there are no gui elements in the upper right corner of the playback pane (drop down list upper left with database, directories etc. is present).
There seems to be no way to select all those fine entries like DoP, bit perfectness etc. ?!?

I also faced the same problem. I owned a Himedia Q5 Pro. When I was using it with Android 5.1.1, i can access the settings menu and change the settings as i wish.
The problem like yours appeared when I upgraded to Android 7. I think this software cannot support Android 7 yet.
