PC speakers make buzzing sound

I have a Dell Optiplex 3070 running Windows 10 with all the latest MS and Dell updates. I have a pair of speakers connected to the audio jack which have recently started to buzz. Last week when they started to buzz the buzzing faded when I moved them away from the monitor. This week, that makes no difference - they now buzz even louder irrespective of where they're placed. I've purchased new speakers but that hasn't helped. I've disconnected and powered down the monitor but still the buzz. I have reverted to the previous version of the RealTek drivers but with no success.
I suppose it could be that the Dell sound card has developed a fault but that does seem to me unlikely but I could be wrong.
Anyone any suggestions please?

I think all that replied were on the button with the solution. After a bit more poking about I discovered that wiggling the audio jack started/stopped the buzzing. Seems there is a dry joint between the jack socket and the motherboard. A hi-tech cocktail stick wedged in place makes the connection which is good enough for now until either the cocktail stick fails or the PC is retired. Thanks all
