Hi @awesome-manuel , Thanks for the PR. After a quick review, the code LGTM. I will check at runtime. FTR the core team is working more on RiotX now, but if all is Ok, I will merge the PR anyway.

Pb I see so far:

mp3 playback does not work. I haven't tested other format yet.
When scrolling, the button state (play/pause) is not restored

What do you mean by that? When I scroll everything just keeps working like you would expect it

mp3 playback does not work. I haven't tested other format yet.

I usually use audio/mp4. Do we really need mp3 support because the Android MediaRecorder does not even support recording mp3?

Maybe fall back to download in case of MP3?

I have tested mp3 now and it works for me inline just as the other audio messages (m4a, ...). I tested this file: https://ia802508.us.archive.org/5/items/testmp3testfile/mpthreetest.mp3

@awesome-manuel Could you add Support 4 .ogx files like WhatsApp ? It won't playback currently only over a Third Party Media Player possible, I think .ogx is Opus based Audiofile in my mind.
