Properties
continue-on-error
“continue-on-error” gboolean
If enabled, wasapi2sink will post a warning message instead of an error, when device failures occur, such as open failure, I/O error, or device removal. The element will continue to consume audio buffers and behave as if a render device were active, allowing pipeline to keep running even when no audio endpoint is available
