FYI: RoonOS 253 earlyaccess will move to 254 production automatically

@AMP So the question is will we get an EA (B257?) to fix the HDMI issue for those that need it or is the HDMI issue not an issue in the current EA (B255)?

Roon OS 1.0 (build 256) production did fix HDMI audio on the Zotac ZBOX CI331.
