Hi, I don’t know if you’ve seen yet but I’ve replied to your query on the Hyperion Github. Just to avoid an unresolved issue floating on the forum I shall paraphrase here:
The June update brings in the underlying changes needed to fix the a/v sync issue with Hyperion.ng, so then you just need to update Hyperion.ng from my installer to get the other half of the fix. I couldn’t update Hyperion.ng in my installer before hand, because without the kernel updates to go with it that breaks AML grabbing altogether!
Update instructions here! I hope that works for you as it has for others on these threads.
