I have an Vu+Ultimo 4K and loaded with OpenPli 7.2 latest update. I have BBC channels via 27,5W working rather good. But after installing IPTV I noticed that the HD-channels on 27,5W lost the sound. Totaly silent. SD channels ok.
This is not a serious problem for me, becaused I moved the IPTV-channels to another box (DM900uhd). I just wanted to report.
