Every time I press Play/Stop in Audacity there’s is a pronounced tic or pop. Not only is it irritating, but makes it difficult to ascertain if it is just this nuisance or an actual audio artifact in the file. This occurs in all files and all audio file types. It also occurs in other applications, but is not nearly as pronounced. I even notice it when a Facebook audio notification comes in.
I recently installed a Behringer UCA202 to offload analog/digital conversion, and it has been working flawlessly until about an hour ago.
Thoughts please on what could be causing this issue and possible fixes?
