Found this video that looks to correct the problem. I'll make with the volume setting changes later today.
I'm surprised it is still a thing, with it being out this "long". Unless they would need to weed out a lot of audio that goes to the devices because they didn't organize it well enough.The weird volume adjustment thing sort of works. I still get obnoxious rumbling. I added double-sided black tape around the exciters and it still happens! AtGames is sending too much audio to those exciters. They're not speakers.
Looking at videos, looks like the OTG is pretty lag free. Were you talking about the Cloud streaming in regards to lag?
And if the OTG is working, one can play the AfM tables on the AtG LP machine. No haptic, but it'll look bigger and cleaner.But the A1Up machines are gorgeous and they are way easier to "pick up and play". I went a bit crazy and got AfM and Marvel. Love them.
