Mkysimes That's the shame that USB audio doesn't have system sounds and BT, otherwise that would be an awesome option, even USB to SPDIF converters would have made this an excellent choice.
Some other head units have overcome this limitation; they have all the sounds on USB audio without volume control (DUDU7 can also not control volume over USB audio). This is beyond what DUDU can do, as the unit is developed by FYT and there are hardware limitations.
Maybe there is another unit in development that can overcome 48kHz limit and USB audio routing. This surely can be done, as it is done by another Chinese brand. 96kHz on all outputs, and 192kHz on USB audio with system sounds and BT sound. You play 44.1kHz, you get 44.1kHz output, you play 96kHz, you get the same without up/down sampling. I wish DUDU/Mekede can develop a unit capable of this, as the software and experience is much better than anyone else.
