Thank you for your great work!
I installed it internally on my MXQ. Everything works except one thing. I have a video with x265 and AAC 5.1 for this I could not play the sound, picture is playing perfectly with the subtitle, but no sound. The MXQ is connected to the amp by HDMI and all other video plays with sound for AAC 2.0, DTS and DD. I can play the same video on Mini MX 1G with your LE 7.0.2.003 perfectly on the same amp with HDMI connection. I used the same sound setup on both MXQ and Mini MX in Kodi.
