HTML <audio> tag doesn’t work when your files are in a Dropbox/iCloud folder. It renders well in the preview mode, but does not play and shows “Error”.

I’m running MultiMarkdown Composer 4.5.12 on macOS Mojave 10.14.6.

Marked 2 doesn’t have this problem.

    Add a fake link to an image (e.g. <img src="test.png" alt="" />) and then close and reopen the file. This should cause Composer to ask you to allow permission to access the entire folder (and not just the actual file you opened).

    If this is a sandboxing issue, that should fix it.

    If not, then let me know. I don't intentionally disable audio support in the preview, but that is not necessarily a supported feature either.

    No, unfortunately it’s not a sandboxing issue :< I gave the program full access to my disk in the macOS settings menu, but it din’t help.

    I know it’s a specific request, and I personally can use Marked after all, but it would be great if there was no such problem. Native HTML audio is a great help when taking notes on phonetics, music, physical acoustics, etc.

    I was working on some similar things, and circled back around to this.

    When I test, it is a sandboxing issue. Adding a local image triggered Composer to ask for permission to access the disk (since audio wasn't something that Composer looked for.) Once I did that, the audio file played.

    Marked 2 isn't sandboxed, so it doesn't have to play by Apple's rules...
