I loaded a video file with an unusual 8 channels instead of 7.1 and 3 other AC-3 audio tracks but smart cutter doesn't detect any audio track, it displays no audio, the resulting edited file has all the streams and subtitles and works perfectly with no problems, it is just hard to edit with no sound:
