No Audio Frames Received When Using aiortc for WebRTC Communication

[ilyas-dh]

I'm experiencing an issue where no audio frames are being received by my Python WebRTC client using aiortc. The setup involves a Python script that is supposed to establish a WebRTC connection, receive audio streams, and process these frames. However, despite successfully establishing the connection and seeing that the track is live, no audio frames are being received. Additionally, when I attempted to send audio from this client, the audio heard on the working remote client was severely distorted.

Steps to Reproduce:
Set up a WebRTC connection using aiortc.
Configure the client to receive audio streams from a remote WebRTC server.
Add a track to receive audio, set the direction to recvonly, and attempt to process incoming audio frames.
Observe that the connection is established, but no audio frames are received or processed.

Expected Behavior:
Audio frames should be received continuously on the client side when the audio track is live, allowing for further processing or playback.

Actual Behavior:
The WebRTC connection is successfully established.
The audio track appears to be live.
However, no audio frames are received or processed, even after waiting for a significant period.

Details:
Codec in Use: Opus with default parameters.
Client Library: aiortc
Connection Status: Successfully connected, ICE connection completes, and the track is marked as live.
