Oh well.
Yes, this is the right parameter and it's expected that below ~500ms shuttering happens. It's because the plugin has to build a buffer of the airplay frames. Such RTP frames are sent using UDP protocol, so no guaranteed delivery. There is a mechanism to ask again for missed frames, but it means that you must do buffering to give you a chance to ask for and received the missed ones because if you have a hole of 100 frames between say frame 900 and 1000 but you've already sent frame 1000 to LMS, then it's over because the interface with LMS is HTTP, so frame numbers do not exists, ordering is implicit by order of sending HTTP data. Anyway, you can also tweak the "buffer level" parameter which adjust buffering inside LMS this time. Normally it does not affect playback start in a deterministic way, but here it should because the source is hard realtime LMS 7.7, 7.8 and 7.9 - 5xRadio, 3xBoom, 4xDuet, 1xTouch, 1 SB2.
