When fetching the Stream-Details from File, the number of channels stays empty => I have to insert the number of channels manually, otherwise my renaming template won't include the number of channels.
Expected behavior
Number of Audio-Channels should be gathered, shown and saved.
MediaElch Version:
2.8.5-dev (nightly)
2.8.4 stable
Operating System:
Windows & Linux (Ubuntu 20.10)

Thanks for reporting! Will look into it at the of the week. May be due to a MediaInfoLib update... :-/
My test
Channels Audio

@ticao2 Thank you! That helped to find the bug in 5min. Fix is on the way.
Fixed by #1178
great job !!
Sorry for this regression. Should not have happened in the first place. :-)
@bugwelle For your information:
I usually have 7 or 8 ME in operation. At least 6 ME.
All in Portable mode. In various versions dev.
1 or 2 for the total collection of ready-made Movies.
1 for Documentaries.
1 for Series.
1 for Concerts.
1 for Movies that are still without subtitles.
1 or 2 for new Movies.
Today I have 10 ME because of the tests I did.
I don't use it for music. But if necessary I can install it for testing with a few discs.
Windows 10 Pro 64.
So it was easier to see in which dev the problem started to occur.
So if you need any information or testing, just ask. :-)
@ticao2 Thanks! :)
