Hello aleroux, I'm having the same issue with my Amplifi 75, bought it second hand to get me through the next few months with COVID-19. It worked fine for the first couple of days, but then started cutting out, at first only occasionally, but now it has become not usable. any chance you can post the SD card image on this thread in a zip file or similar? Would love to try it before I toss the damn thing.
Thanks,
Christian
