Please Make It Work on Audio M4A/AAC Files Too about lossless-cut HOT 4 CLOSED

Can you open developer tools (ctrl+shift+i / cmd+alt+i / f12) and see if there is any additional output from ffmpeg when cutting?
Or if possible please share the file or a cut part of the file that can reproduce the problem

from lossless-cut.

Here's the output:

I have now implemented a fix for this issue (aac/m4a files) and it will be included in the next release.
