Like an option 'keep sync to soundbar at all times' when first handshake is completed
No sorry, that makes little sense.
First, you wrote "during boot" .. during boot of which sources ? you said some sources sync and loose sync during boot ? yes they go from 480p or FHD to 4K, typical sync time for a device in the middle is up to 5sec, so when ever some res change, hdcp change, chroma change, color depth change, etc... there could be up to 5sec sync time at each occurrence, that is typical and absolutely normal.
and then you wrote, "however can you stop this sync to propagate to audio out", if incoming audio/video signal changes and if that signal audio is extracted to audio out, then no, we cannot prevent audio out from syncing again.
You said popping noise or cracking sound I suppose, that happens when an AVR or soundbar is currently decoding PCM and there is new signal in bitstream, the time it shifts its internal decoder you can hear such sound for a sec. same if current signal is bitstream and then you resync with pcm.
Some AVR even replace that popping noise by a beep when they switch decoder. However if you have a well designed source such as oppo203, you will never heard such sound because it will mute sound while changing format and that is what most of sources are supposed to do. in real life however, a source like STB very rarely does that.in such case the work around is to force bitstream always or pcm always and then you won't have such popping noise as there won't be any changes anymore.
Anyway, I sent you test firmware you can try by PM, see if it helps a bit without changing any settings, if still not, set/force your source to audio format you want always.
