HDMI Multichannel audio: any update?

Hello,
testing now the Volumio software on Pi and so far it looks good, but i found it does miss one thing: HDMI Multichannel (from 4.0 to 7.1) audio. I have read various topics of the past that has no or little reply but it seems that Volumio can do multichannel on USB, so it is a matter of software implementation. On this aspect several progress has been done in the last year - at the bottom some links i have found relevant to the topic - so i wonder if Multichannel HDMI Audio Out will be added to Volumio anytime soon.

Thanks for reading

Not really, Volumio, and a load of other audiophile solutions, only work with stereo output.
This is not likely to change soon.
