Steps to reproduce

  1. Start Element and enter a 1:1 room;
  2. Wait for the call from the other party;
  3. After receiving the call, tap "Answer" in the timeline in the conversation.

Outcome

What did you expect?

n/a

What happened instead?

a) If this incoming call is answered according to step 3, then I cannot hear the other party’s voice during this call, and the other party cannot hear my voice. However, the call time will still be displayed as usual.

b) If you answer from the lock screen or notification banner, then everything is fine.

The network environment during the test was Wi-Fi, with self-hosted Synapse and coturn.
I have tested this problem many times using the web client (1.11.50) and Android client (1.6.8), and I can reproduce the fault with a high probability.
Estimated failure rate: No sound is heard approximately 9 times out of 10 calls.
This glitch only occurs with audio calls. If a video call is established through the above steps, there will be only image but no sound.
