Description:

While in chat, sending a sound message always fails. The circle never disapears until page reload.

There are 2 error messages in Console (F12), pasted them below.

There should be a notification for the user, not only on console.

Seems that RocketChat App does not ask for permission to use the microphone. But even so, it should send a mute sound, not only let the circle spin.

Happens in Iframe and directly in RocketChat server domain.

Steps to reproduce:

1. Enter any room
2. Push the Microphone to record sound
3. Send it. It fails, and circle keeps spinning.

Expected behavior:

Ask for permission to use microphone -> Record -> Send sound recorded to the room.

Actual behavior:

Throws 2 errors in Browser Console, and circle spins forever. No error registered inside Rocked Chat Admin Panel, would be great to see it there too in case the error happens to a visitor, and not to a Admin user.
