I have noticed that if I am recording using the built-in recorder on Banana and change a source or destination routing to a different device the recorder appears to stop recording. However, I think it is still recording as when I spotted it and put it back into record there was no noticeable gap between the first and second files created apart from a very slight drop out, far shorter than my reaction to seeing the issue.
This has happened on both source A1-A3 and destination A1-A3 re-selection.
