Just wanted to say, that I also installed the nightly build on my Beelink GT1 mini (S905X2).
Mad a fresh install and also had to edit the config.txt to get the correct screen colors. Besides that, I didn’t had any issues.
Only big issue (for me) is, that multichannel PCM isn’t working, like I described here:
Happy to provide logs and other information not only for this, but other issues as well.
