I can't seem to reproduce any audio issues with that command. After running that, both sample.mkv and sample.avi play fine in ffplay and mpv. I don't think there is any audio within the first 3 seconds of the sample you gave me. I get the warning you mention, but the LFE channel appears to be silent throughout the sample so I'm not sure if that is the issue. Thanks, James
