It causes significant regressions in HD audio, so I will remove the feature in the next update unless I can find a good way to deal with it. The A2DP app and Kodi are tightly coupled: the current Kodi builds in staging do not permit this anymore.
Pi works by fluke (CAEPiSink is brought up before ALSA sinks), but this will cause issues on a Vero, Apple TV, PC etc unless the user manually selects HDMI or SPDIF again.
I'm sure I'll think of something..
The problem here is a lot of them look the same, but have different chipsets and you only discover this once you plug them in. I have three that look the same; only one worked. I will be sourcing some of these to sell in our store for users that are unsure.
