Hi! Thank you so much for your reply! Regarding your questions (both trains that we have, has show the same behaviour): 1- the train react/recognize all five action brick (of course, the yellow/sound action can be checked only when sound i working) 2- actually, now I recall that sometimes (now not sure if this happens with sound working or not), action brick green and blue are not recognized and train goes over without any action done, but this is not very frequent; may be room light? dust?; 3- beyond point 2, the only clear problem is the sound! showing a behavior of: not working for weeks / months; then it comes back and works for a few minutes / hours and then it goes again. Thanks for your time and support!

Hi, my name is Walter and I´m new in this fantastic forum! I´ve landed here because of the Powered Hub from the Set 10874, hoping to find a solution to my problem. As described by many people across web, this Hub shows two common issues. 1, the color sensor problem; and 2- a sound problem, which is my situation. I´ve 2 item (1 10874 purchased set and 1 received as replacement from Lego) and they both show the same problem. The sound comes and goes without logical reason. Did anyone here gets the same sound problem? and, because people here were able to hack the hub, did any of you find any reason/solution of this No Sound situation? a code issue? an electronic issue? Thanks in advance for any support, Walter.
