@FiiO
I had your email in spam. But I got it and tried.Of course the problem is there L track play in R channel and R track plays in L channel when output is Native DSD. It is correct when playing it in DSD to PCM mode. This behaviour is player independent and reversed channels are also in your FiioMucic app.
Some days ago I wrote you exact plan how to check it here

I will repeat it once more again:
Another possibility how to check is with Fiio Music android application. You can do it with ANY DSD track you have. No need to upload anything.
1. Play any DSD track on PC or elswhere.
2. Note positions what is on the left and on the right.
3. Play the same DSD track in FiioMusic - USB output Native settings
4. You hear channels are reversed
5. Switch USB output to DoP DSD over PCM.
6. Channels are still reversed.
7. Switch USB Output to D2P DSD to PCM conversion.
8. Channels are correct.
You can do this also with any other players which support DSD and switching DSD mode.
DSD bitstream is sent to wrong channels, PCM bitstream is sent correctly.
Other users also confirmed this really big bug. AND IT PLAYS CORRECTLY IN YOUR OWN Q1MKII. If you dont understand my test case then play the same files in both Q5s and Q1mkII.
It would be good to correct this stupid bug until info about it will spread over the net.
