"Error downloading audio" when recording a voice mesage

[RayBB]

Steps to reproduce

1. I was in a 1:1 non encrypted chat
2. I clicked the button to record a voice message twice and talked for about a minute.
3. When I clicked stop recording it said: "Error downloading audio"

Note: This was the first time I send a voice memo since I opened the app. The 2nd attempt to send a voice message worked fine.

I have the same problem on 1.11.65 on Linux, using Firefox:

It's notworthy that I can download the file and it'll play just fine in VLC, so not sure what the error actually is.

so not sure what the error actually is.

Without sharing the logs, neither do we.

The original logs for this issue have expired

[madduck]

Let me know what you need. There is nothing in the browser console, and /rageshake doesn't work:

PS: I accidentally filed this under "not in a browser" but I am actually just using Firefox, with my own 1.11.65.

@madduck you didn't file this issue, it was filed in 2023 by @RayBB.

If you want to contribute logs to this such that it isn't closed you'd need to reproduce on a client with rageshake configured, e.g. app.element.io or better yet develop.element.io
