8.2.2 has resolved the audio issues for M8 and M8S-PLUS. Thanks Demetris for the great work.
What issues were resolved? I have an M8 box now with the 8.2.2 image. Still have the same audio problems: I.e. DTS and DD does not work over the S/PDIF optical link. I can now choose S/PDIF as audio output but I still get only a short noise / screech and the silence whan playing DTS or DD content. GUI sounds work fine. Demetris
