delete the custom channel in
Thanks zoltan, I forgot all about those custom channels I typed in a while ago.
I checked the codec details of one of the files that is has no sound and I can't see anything that is different from files that do have sound. Here are the details of the file. Ill play the file and inspect the kodi log file to see if there is any other information.
h.264 Mpeg-4 AVC
Frame rate 30
Planar 4:2:0 YUV
MPEG AAC (mp4a)
