Hello. I own two Roku's. One is a 3810x 4k Streaming stick and the other is a 3920x Premiere. Under the last update, My 3920x upgraded to 10.5.0 build 4201-91. Videos using Dolby Digital Plus audio play perfect but my 3810x is using 10.5.0 build 4201-50 which is causing problems with no sound on videos using Dolby Digital Plus. Is there a way to get my 3810x to use the same upgrade as the 3920x build 4201-91?
