When a combinator (decider or arithmetic) has an output connected to the input and is constantly updating (like for a clock) the sound starts glitching. This becomes very annoying when working on a circuit design that has such behavior. Tested on linux and windows.

Thanks for the report, however this is not a bug.
When a combinator is updated often, its working sound speeds up, up to 2 times speed.
As far as I can tell this behaviour hasn't been changed in 7 years.
