In a 1:1 desktop voice or video call, muting the audio triggers an Android notification.

[dutchalthoff]

Steps to reproduce

1. Have both the desktop and Android Element clients signed in to the same account.
2. Start a 1:1 (voice or video) call on the desktop client.
3. Mute the audio in the desktop client.
4. Check the Android phone for notifications.

When I asked the #element-android:matrix.org community about this, the response was, "it's always been like that," so it seems like I'm not the only affected user.

Outcome

What did you expect?

I expect no notifications for this event.
Repeatedly muting to silence background/keyboard noise is common in an audio/video desktop call.

What happened instead?

Both parties in the call get an Android notification every time someone mutes a 1:1 desktop call.

Yes, this is caused by the combination of matrix-org/matrix-spec-proposals#3291 and element-hq/element-web#7941

on the client side we're incorrectly assuming all encrypted event types are messages, which causes this type=org.matrix.call.sdp_stream_metadata_changed to be rendered as a notification code ref
