When I play with my hardwaresetup (see below) videos, no sound comes. The Gui Sounds works and I can play music files without problems.

LibreELEC Alpha 7.90.009 (LibreELEC-RPi2.arm-7.90.009)
Raspberry Pi 3 Modell B
GPU Broadcom Dual Core VideoCore IV, OpenGL-ES 1.1/2.0, Full HD 1080p30
HiFiBerry Amp+ Class-D power amplifier

With LibreELEC 7.0.2 (LibreELEC-RPi2.arm-7.0.2) and the same hardwaresetup it works fine.

Steps:

Add the Device Tree Overlay to config.txt: dtoverlay=hifiberry-amp
Set Audio output device to "ALSA: Default (snd_rpi_hifiberry_amp_Analog)"

I have found that it is exclusively audio streams, which have a higher samplerate than 44100 Hz. Audio tracks in videos with a sampling rate lower than 48000 Hz are output via the HiFiBerry.

More details are available in the Kodi debuglogfile (kodi.log.7z).

Video files examples ("ffmpeg -i videofile"):
