Hier soir j'ai branché la HO du X7 sur une line in de ma chaîne de salon, ça m'a permis de trouver le délai avant rupture de communication bluetooth.
J'ai donc éteint l'écran, lancé la lecture avec la RM1, fait pause et au bout de 25 secondes j'ai entendu sur mes enceintes un petit bruit parasite très court. C'est ce qui marque la rupture, quel que soit le X7 branché (l'un avec AM3 et l'autre avec AM5). Avant 25 secondes je peux relancer la lecture avec la telco, mais plus possible après sans rallumer l'écran.
J'ai rebasculé les deux X7 en firmware 2.0 (android 4) et tout fonctionne correctement.
Je vais préciser tout ça sur de forum de FiiO.
Petite précision pour celles et ceux qui envisageraient de profiter des bonnes occasions des PA mais qui seraient refroidis par tous les posts signalant des bugs sur les firmwares 3.X.X, le dap sous 2.0 est totalement fonctionnel.

X7 supporting Android 5.1 had actually already been a must-do mission way before X7's launch. Back in the middle of 2014, we had already started the software development of X7. However, for consideration of stability of the system and the sales plan of X7, Android 4.4 was the only and the best choice back then.
In March 2015, Google released the Android 5.1. But at the time, it's much harder to develop the Android 5.1 than Android 4.4 and it certainly would be more time-consuming. RK did not provide technical support for RK3188 to run with Android 5.1 until July 2015, so we didn't have much time left before X7's launch. Besides, our software team will have to take care of the software upgrade of other models. Therefore the Android 5.1 for X7 is a bit left behind. We're so sorry for keeping you waiting.
Today, the Android 5.1 finally can be realized on X7! To better satisfy the need of our customers, we have improved the underlying framework and design a brand-new audio architecture which will bring you excellent music experience. However, since the underlying design of the firmware is very different from the Android 4.4, the firmware upgrade can only be realized by burning with the desktop upgrade tool. Also some functions might be different after the upgrade, please find the following introductions for your reference.
Statements before upgrade:
Though this firmware is based on Android 5.1, it still needs time for perfection. Therefore, we have defined it the public beta version. You can choose to upgrade or not according to your personal preference. Also you're welcomed to share your opinions and suggestions about this firmware with us.
This firmware upgrade can only be realized by burning with the upgrade tool. All data on X7 will be erased after upgrade. So please backup your important data stored on X7's internal storage and remove the SD card before the upgrade.
The FW3.0beta (Android5.1.1) solves the problems left from the FW2.0 (Android4.4.4) and adds the following functions:
No SRC for third-party music applications
Adopted the incremental media lib update (only new songs will be updated), and added recently played playlist
Added sorting by alphabetical order (among different languages)/file name/track number /number of tracks in album. (Both ascending and descending are supported)
Added the Maximum volume and customized volume setting in FiiO music
Added the continuous volume adjustment when screen-off
Added the manual OTA upgrade(Technical support->Firmware Update->Online Upgrade, OTA upgrade will be available next time)
Added instant switch between Android mode and Pure music mode (no reboot required)
CUE tracks can be added to the playlist directly
Press the Play button to wake up X7 from hibernation, press again to play music without lighting up the screen.
Improved the USB DAC delay
Improved the power consumption of standby and music play, playtime can last for 90 min longer.
Improved the pull-down menu, where common used functions can be switched directly
Improved the stability of Google Play.
