I reported the same issue in the latest ROM update thread (http://forum.zidoo.tv/index.php?threads/a-new-firmware-version-v1-2-7-for-zidoo-x7.5716/) and aside from a comment that they will look into it, have not heard anything (that was 2 months ago). If you select a non-lossless format such as Dolby Digital or DTS, the sound is fine (which would be the same with connecting directly to TV), but that is not the point - it doesn't play HD audio codecs properly. @EJ Barrois While 3d isos play in 3d fine for me (with the above audio problem), 3d MKV files do not play properly in 3d (or 2D for that matter). Can you check that the 3D MVC MKVs (made by MakeMKV) play properly in 3D
