Crackling noises when listening to audio through Safari
This seems to be a common and old and problem in apple computers. It seems to manifest itself in different ways and, by reading various threads as old as 2019, on different computers and OSX versions.
I use Logic Pro too but there I have no problem at all! I only see it on Safari audio, e.g. Youtube. But it is possible that it happens on other streaming apps such as Spotify, etc. which I do not use. I guess it started on Catalina. I had, almost at the same time, installed OBS Studio and created another multi output device. So I removed it, but of course this did not help, which probably confirms that a SW update had triggered it, as I mentioned, i.e. probably Catalina or a Catalina update.
I installed Chrome and I don't see the problem there at all. So I find it very surprising that Apple haven't corrected a problem on their main browser!!
I am on iMac 27'', Late 2013. Catalina 10.15.7. My audio device is Behringer Xenyx UFX1204.
I have had no audio problems since I put together the studio in late 2013 and not until November, 2021 when the crackling noises started appearing.
