Kodi 18 Broke my sound!

[Skywatch]

After using xbian-config to update and upgrade today I no longer have any sound.

Looking into the settings I see the audio output is correctly recognised as ALSA:Default(snd_rpi_hifiberry_digi Analog). Channels are correct at 5.1 too.

But when I check the setting for passthrough it will not allow me to select this hifiberry as output. It only shows 'PI:HDMI' and even that is greyed out.

I can't think of what to try. Any ideas out there?
