We've updated demo server to the latest build 5.2.1131 and WebSDK 2.0.212. In this case, the problem is reproducing randomly in Chrome 98.0.4758.80 on MacOS 12.2. Seems like the issue is ih hardware H264 encoder parameters. There are the following workarounds:
1. Publish VP8 codec instead of H264

    session.createStream({
        name: streamName,
        display: localVideo,
        ...,
        stripCodecs: "H264"
        ...
    }).publish();

2. Or disable hardware acceleration in Chrome settings
3. Or set publishing constraints explicitly at least 640:

    session.createStream({
        name: streamName,
        display: localVideo,
        ...,
        constraints: {
            audio: true,
            video: {
                width: 640,
                height: 360
            }
        }
        ...
    }).publish();

This seems the best workaround.
Also, we noticed that Safari 15.3 on MacOS 12.2 may not send audio packets (this occurs randomly). The explicit constraints setting is also helps in this case.
