Using the same Libreelec release (Alpha 5) with Kodi Krypton beta 1 on
a Solid-Run Cubox-i (imx6 based) and on a WETEK Hub (S905 based)
my UAC222 USB DAC does not work with the latter. An USB DAC
is recognized on the Hub and can be selected. But sound output
is still only on the HDMI. On the Cubox-i everything works fine
an sound is going thru the DAC.

Please help.

AMLogic has no USB audio support. No matter what you do only internal audio will work. This is cared for in AESinkALSA. You can patch the sink, but be prepared: Audio will heavily stutter and won't be usable.
