What did you expect?

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. {FFDA764C-39D7-BFEB-2CCB-B7CB747864E9}

b) If you answer from the lock screen or notification banner, then everything is fine. {67C71C71-61F7-7AD1-1987-DEA2F0665257} {7CD59C46-F7C7-DD7D-A7FC-B0E5084E9EB6}

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.
