When joining a channel, some users might encounter the error m_AudioClient->Initialize() failed with the result The parameter is incorrect. When this failure occurs, vxa_capture_device_open and VivoxClient::VoiceProcessor::OpenAudioUnit also fail.
The full error sequence is similar to the following code snippet:
