Thank u all

If you could pass on a video or an audio recording of the pulsating sound you're receiving from a cold system that would help us figure things out faster. Regardless can you please pass on your full systems specs inclusive of your OS and audio equipment? If the pulsating sound is evident with some of your appliances around the house then you can be sure that the issue is found to be within the houses wiring or that you have a grounding issue.

One possible solution outside of a rewiring job is to introduce a pair of ferrite chokes to your audio cables at each end to negate electromagnetic interference.

Disconnect audio cable. Is the pulse sound still there?

How did you connect the bose speakers to your PC?
