Can't install ARISE Sound system on MIUI9 beta

[itzram]

I have flashed zip through twrp. I have tried both aroma and non aroma installer. I have skipped all other than core module, Viper4Arise and Dolby Atmos. Log in twrp recovery showed installed successfully when I restarted to system I found no apps installed. I have faced same problem with redmi note 3 which is running on miui 8 global beta. Then I flashed MIUI8 global stable version and there is no problem with installing. Why this is happening in miui beta rom only?
