Remap? Maybe you need downmix.

Try -downstereo

Put the log to know the input layer and formats.

Correction: the audio is 3.1 - Front & Side L R. I decoded part of it and found the L voice channel (must be channel 0) silent. I did come across a 2.0 mix of this audio, it had voice in one channel. Downmixing as it is probably won't do. How do I go about mixing or remapping this? Other than decoding to WAVs and replacing the silent channel. Mono? I didn't keep the log and the source AC3 but if you think it can help I'll get it.

3.1 with FL channel silent?
Is strange, without a sample I don't know the problem.

BTW eac3to have a way to remap channels, for instance:

eac3to input output -1,2,0,3

that send the input FL channel (0) to FC channel (3) in output

If I use VLC 228 or lower, then there are no errors in the recorded files.
But if I use VLC 306 or higher, then there are a lot of errors in the recorded files ([v01] Video overlaps for 7 frames at playtime 0:01:30. <WARNING>).

Could you explain the nature of these errors?
Are these realy errors in the records or is this an incorrect work of the eac3to?

Here are two videos recorded in 228 and 306

Tebasuna, gracias! Do I need anything more to successfully apply -1,2,0,3? I get "Command line parameter "1,2,0,3" is unknown."

@Masutin

Sorry, seems the remap parameter need at least 6 channel even if source have only 4:

eac3to input output -1,2,0,3,4,5

tested over a 3.1 input.
