I use tvheadend for 8 or 10 years and I like it very much.
I have some problems with tvheadend4.3 in DVB-S, The same does not find all the frequencies found in tvheadend4.2.
In both tvheadend I have a problem with the lack of audio audio in some channels.
Tried help on the kodi forum.
More without solution.
If anyone here can help to resolve it, I will be very grateful.
