Bookworm 6.12.y for the uConsole and DevTerm

I’m having an interesting problem and I can’t quite figure it out. I suddenly started getting scraping/scratching sounds out the speakers. Like a pulsing when the processing gets higher or when there are more screen redraws. It definitely some crosstalk. It started with the 6.12.17~ kernal, and other than SDR stuff I don’t have other packages. If anyone has ideas I can cry I’d be grateful to try. I don’t know everything Linux but know enough to break stuff and fix it half the time. Humble enough to ask for help.
