The information (from a colleague who starts the meeting and records it):
• MacBook Pro with M2 silicon chip
• MacOS 13.3.1(a)
• Local recording using latest version of the client
• Audio: ...using their VOIP protocol using the Mac's microphone and speaker (standard audio)
Yes, it's always reproducible. If I do a meeting by myself, the audio works. If I do a group, there is no audio.
