I2S and OMXPlayer\MMAL

  • Hello. RPi 2 @900MHz
    I have this Hifiberry analog: Raspberry Pi Expansion Board
    My sound system connected to this card via RCA.

    Added dtoverlay=iqaudio-dacplus to /flash/config.txt
    Switched to ALSA in sound options.
    Problem is i have no sound in movies via I2S with OMXPlayer, working on HDMI to TV only. 3.5 mini-jack also output also not working.
    Switched to MMAL player - good, I2S have sound and my AC sounds cool.
    BUT!
    It is impossible to use MMAL because every few minutes i have 0.1sec stutters.
    Even if i press "volume+" key - film starting lag when volume bar is appeared on interface.

    I see 2 options:
    - I2S must send sound via OMXPlayer
    - MMAL must stop to stutter

    How to fix that?
    Thank you. Sorry for my english.
