Hi Maven,
apologies for the English, I am a huge fan and avid user of your build.
there has been a breakthrough in some common shield audio issues, and they’re releasing test builds now for Alpha 21 with a focus on true-hd stutters, but in testing this stabilizes all passthrough audio/video for shield users specifically - as it was found the audio buffer in this android shield. Really really bad. Wondering if you’d consider incorporating this, as it’s a shield-specific fix that is working wonders for us testing it - see: https://forum.kodi.tv/showthread.php?tid=371292&page=38
not sure if it’s backwards compatible with your 20 release, but I think it will solve problems for many shield owners, take a look if you can!
Thanks again!
