I have a problem with foobar on android.
I' m trying to read files from a tp-link router with media server started.
It works fine with .mp3 and .flac files but .m4a (ACC) and .opus files don't show up when browsing for files. Both these files were converted from flac with foobar on my PC.

If I rename a .m4a file to .flac it becomes visible but I get an (obvious) playback error.

Is this a bug or I'm doing something wrong?
Thank you.

For some reason foobar on windows10 is unable to browse the tp-link UNPN server so I'm unable to verify if windows version works.
