The subject line says it all. I received this error (which is detailed below)
recently while executing a flowgraph of a project which has been running
successfully.
Several of the blocks have their output buffers assigned to values other than
their default. This was necessary to permit this particular application to
operate properly.
I don’t know why I suddenly have this issue. it seemed to arise after I had
some complications occur due to a “sudo apt upgrade” that I performed.
I realize that this explanation is vague but I don’t know where to begin to
troubleshoot this issue. I can make the problem go away by removing the buffer
setting from an analog source block but then the application ceases to work
properly.
Please help point me to the right path here.
